The old software must be used for the dump, and the new +software for the reload. + +This was a major problem for RedHat and Debian, because a dump and reload was +not required by every upgrade and by the time the need for a dump is realised, +the old software might have been deleted. Debian had certain rather unreliable +procedures to save the old software and use it to do a dump, but these +procedures often went wrong. RedHat's installation environment is so rigid that +it is not practicable for the RedHat packages to attempt an automatic upgrade. +Debian offered a debconf choice for whether to attempt automatic upgrading; if +it failed or was not allowed, a manual upgrade had to be done, either from a +pre-existing dump or by manual invocation of the postgresql-dump script. + +It is possible to run different versions of PostgreSQL simultaneously, and +indeed to run the same version on separate database clusters simultaneously. To +do so, each postgres instance must listen on a different port, so each client +must specify the correct port. By having two separate versions of the +PostgreSQL packages installed simultaneously, it is simple to do database +upgrades by dumping from the old version and uploading to the new. The +PostgreSQL client wrapper is designed to permit this. + +General Architecture idea +------------------------- + +The Debian packaging has been changed to create a new package for each major +version. The criterion for creating a new package is that initdb is required +when upgrading from the previous version. Thus, there are now source packages +`postgresql-8.1` and `postgresql-8.3` (and similarly for all the binary +packages). + +The legacy postgresql and the other existing binary package names have become +dummy packages depending on one of the versioned equivalents. Their only +purpose is now to ensure a smooth upgrade and to register the existing database +cluster to the new architecture. These packages will be removed from the +archive as soon as the next Debian release after Sarge (Etch) is released. + +Each versioned package installs into `/usr/lib/postgresql/version`. In order +to allow users easily to select the right version and cluster when working, the +`postgresql-common` package provides the `pg_wrapper` program, which reads the +per-user and system wide configuration file and forks the correct executable +with the correct library versions according to those preferences. `/usr/bin` +provides executables soft-linked to `pg_wrapper`. + +This architecture also allows separate database clusters to be maintained for +the use of different groups of users; these clusters need not all be of the +same major version. This allows much greater flexibility for those people who +need to make application software changes consequent on a PostgreSQL upgrade. + +Detailed structure +------------------ + +### Configuration hierarchy + +* `/etc/postgresql-common/user_clusters`: maps users against clusters and + default databases + +* `$HOME/.postgresqlrc`: per-user preferences for default version/cluster and + database; overrides `/etc/postgresql-common/user_clusters` + +* `/etc/postgresql/version/clustername`: cluster-specific configuration files: + + * `postgresql.conf`, `pg_hba.conf`, `pg_ident.conf` + * optionally `start.conf`: startup mode of the cluster: `auto` (start/stop in + init script), `manual` (do not start/stop in init script, but manual + control with `pg_ctlcluster` is possible), `disabled` (`pg_ctlcluster` + is not allowed). + * optionally `pg_ctl.conf`: options to be passed to `pg_ctl`. + * optionally a symbolic link `log` which points to the postgres log file. + Defaults to `/var/log/postgresql/postgresql-version-cluster.conf`. + Explicitly setting `log_directory` and/or `log_filename` in + `postgresql.conf` overrides this. + +### Per-version files and programs + +* `/usr/lib/postgresql/version` +* `/usr/share/postgresql/version` +* `/usr/share/doc/postgresql/postgresql-doc-version`: +version specific program and data files + +### Common programs + +* `/usr/share/postgresql-common/pg_wrapper`: environment chooser and program selector +* `/usr/bin/program`: symbolic links to pg_wrapper, for all client programs +* `/usr/bin/pg_lsclusters`: list all available clusters with their status and configuration +* `/usr/bin/pg_createcluster: wrapper for `initdb`, sets up the necessary configuration structure +* `/usr/bin/pg_ctlcluster`: wrapper for `pg_ctl`, control the cluster postgres server +* `/usr/bin/pg_upgradecluster`: upgrade a cluster to a newer major version +* `/usr/bin/pg_dropcluster`: remove a cluster and its configuration + +### /etc/init.d/postgresql + +This script handles the postgres server processes for each version and all +their clusters.

Occurrences of B<PGVERSION> in package +sections are replaced by the target PostgreSQL version. Include +C</usr/share/postgresql-common/pgxs_debian_control.mk> in C<debian/rules> to +run a check at build time if updating debian/control is required. + +As B<pg_buildext> invokes B<make> for the B<build>, B<install>, and B<clean> +actions, invocations from C<debian/rules> (which is a makefile) should be prefixed +with B<+> so the sub-makes can talk with the make jobserver. Additional makefile +variables can be passed to B<make> via the B<-m> option. + +Many extensions support B<make installcheck> testing using B<pg_regress>. As +this needs the package to be installed, it cannot be run at build time. +Instead, the tests should be run using B<autopkgtest> from C<debian/tests/*>. + +If C<debian/tests/control.in> exists, occurrences of package names containing +B<PGVERSION> are replaced by lists of package names with the target PostgreSQL +versions filled in.

The name can be +arbitrary. The default cluster that is created on installation of a server +package is C<main>. However, you might wish to create other clusters for +testing, with other superusers, a cluster for each user on a shared server, +etc. C<pg_createcluster> will abort with an error if you try to create a +cluster with a name that already exists for that version. + +For compatibility with B<systemd> service units, the cluster name should not +contain any dashes (B<->). B<pg_ctlcluster> will warn about the problem, but +succeed with the operation. + +Given a major PostgreSQL I<version> (like "8.2" or "8.3") and a cluster +I<name>, it creates the necessary configuration files in +C</etc/postgresql/>I<version>C</>I<name>C</>; in particular these are +C<postgresql.conf>, C<pg_ident.conf>, C<pg_hba.conf>, a postgresql-common +specific configuration file C<start.conf> (see B<STARTUP CONTROL> below), +C<pg_ctl.conf>, and a symbolic link C<log> which points to the log file (by +default, C</var/log/postgresql/postgresql->I<version>C<->I<name>C<.log>). + +C<postgresql.conf> is automatically adapted to use the next available port, i. +e. the first port (starting from 5432) which is not yet used by an already +existing cluster. + +If the data directory does not yet exist, PostgreSQL's L<initdb(1)> command is +used to generate a new cluster structure. If the data directory already exists, +it is integrated into the B<postgresql-common> structure by moving the +configuration file and setting the data_directory option. Please note that this +I<only> works for data directories which were created directly with B<initdb>, i. +e. all the configuration files (C<postgresql.conf> etc.) must be present in the +data directory. + +If a custom socket directory is given and it does not exist, it is created. + +If the log file does not exist, it is created. In any case the permissions are +adjusted to allow write access to the cluster owner. Please note that +C<postgresql.conf> can be customized to specify C<log_directory> and/or +C<log_filename>; if at least one of these options is present, then the symbolic +link C<log> in the cluster configuration directory is ignored. + +If the default snakeoil SSL certificate exists +(C</etc/ssl/certs/ssl-cert-snakeoil.pem> and +C</etc/ssl/private/ssl-cert-snakeoil.key>), and the C<postgres> user is in the +C<ssl-cert> Unix group, B<pg_createcluster> configures the cluster to use this +certificate, and enables SSL. Therefore all clusters will use the same SSL +certificate by default. For versions up to 9.1, symlinks in the data directory +will be created (C<server.crt> and C<server.key>); for 9.2 and later, the +appropriate C<postgresql.conf> options will be set (C<ssl_cert_file> and +C<ssl_key_file>). Of course you can replace this with a cluster specific +certificate. Similarly for C</etc/postgresql-common/root.crt> and +C</etc/postgresql-common/root.crl>, these files will be configured as client +certificate CA and revocation list, when present. (C<root.crt> is initially a +placeholder that will only be used if real certificates are added to the file.) + +=head1 OPTIONS + +=over 4 + +=item B<-u> I<user>, B<--user=>I<user> + +Set the user who owns the cluster and becomes the database superuser to the +given name or uid. By default, this is the user B<postgres>. A cluster must +not be owned by root. + +=item B<-g> I<group>, B<--group=>I<group> + +Change the group of the cluster related data files. By default this will be the +primary group of the database owner. + +=item B<-d> I<dir>, B<--datadir=>I<dir> + +Explicitly set the data directory path, which is used to store all the actual +databases and tables. This will become quite big (easily in the order of five +times the amount of actual data stored in the cluster). Defaults to +C</var/lib/postgresql/>I<version>C</>I<cluster>. + +=item B<-s> I<dir>, B<--socketdir=>I<dir> + +Explicitly set the directory where the L<postgres(1)> server stores the Unix +socket for local connections. Defaults to C</var/run/postgresql/> for clusters +owned by the user B<postgres>, and C</tmp> for clusters owned by other users. +Please be aware that C</tmp> is an unsafe directory since everybody can create +a socket there and impersonate the database server. If the given directory does +not exist, it is created with appropriate permissions. + +=item B<-l> I<path>, B<--logfile=>I<path> + +Explicitly set the path for the L<postgres(1)> server log file. Defaults to +C</var/log/postgresql/postgresql->I<version>C<->I<cluster>C<.log>. + +=item B<--locale=>I<locale> + +Set the default locale for the database cluster.

This will also be the default +encoding of any database you create later, unless you override it there. The +default is derived from the locale, or SQL_ASCII if that does not work. The +character sets supported by the PostgreSQL server are described in the +documentation. + +B<Note>: It is not recommended to set this option directly! Set the locale +instead. + +=item B<-p> I<port>, B<--port=>I<port> + +Select the port the new cluster listens on (for the Unix socket and the TCP +port); this must be a number between 1024 and 65535, since PostgreSQL does not +run as root and thus needs an unprivileged port number. By default the next +free port starting from 5432 is assigned. + +=item B<--start> + +Immediately start a server for the cluster after creating it (i. e. call +C<pg_ctlcluster> I<version cluster> C<start> on it). By default, the cluster is +not started. + +=item B<--start-conf=>B<auto>|B<manual>|B<disabled> + +Set the initial value in the C<start.conf> configuration file. See B<STARTUP +CONTROL> below. By default, B<auto> is used, which means that the cluster is +handled by C</etc/init.d/postgresql>, i. e. starts and stops +automatically on system boot. + +=item B<-o> I<guc>B<=>I<value>, B<--pgoption> I<guc>B<=>I<value> + +Configuration option to set in the new C<postgresql.conf> file. + +=item B<--createclusterconf=>I<file> + +Alternative B<createcluster.conf> file to use. Default is +C</etc/postgresql-common/createcluster.conf> (or +C<$PGSYSCONFDIR/createcluster.conf>). + +=item B<--environment=>I<file> + +Alternative default B<environment> file to use. Default is +C</etc/postgresql-common/environment> (or C<$PGSYSCONFDIR/environment>). +If the file is missing, a placeholder string is used. +%v and %c are replaced; see DEFAULT VALUES below. + +=item B<--> I<initdb options> + +Options passed directly to L<initdb(1)>. + +Per default, B<pg_createcluster> will update the C<pg_hba.conf> file generated +by initdb to use peer authentication on local (unix) connections, and md5 on +TCP (host) connections. If explicit authentication config is included here +(B<-A>, B<--auth>, B<--auth-host>, B<--auth-local>), the C<pg_hba.conf> file +will be left untouched. + +=back + +=head1 STARTUP CONTROL + +The C<start.conf> file in the cluster configuration directory controls the +start/stop behavior of that cluster's postgres process. The file can contain +comment lines (started with '#'), empty lines, and must have exactly one +line with one of the following keywords: + +=over 4 + +=item B<auto> + +The postgres process is started/stopped automatically in the init script. + +When running from B<systemd>, the cluster is started/stopped when +B<postgresql.service> is started/stopped. +This is also the default if the file is missing. + +=item B<manual> + +The postgres process is not handled by the init script, but manually +controlling the cluster with L<pg_ctlcluster(1)> is permitted. + +When running from B<systemd>, the cluster is not started automatically when +B<postgresql.service> is started. However, stopping/restarting +B<postgresql.service> will stop/restart the cluster. The cluster can be started +using B<systemctl start postgresql@>I<version>B<->I<cluster>. + +=item B<disabled> + +Neither the init script, L<pg_ctlcluster(1)>, nor B<postgresql@.service> are permitted to start/stop the +cluster. Please be aware that this will not stop the cluster owner from calling +lower level tools to control the postgres process; this option is only meant +to prevent accidents during maintenance, not more. + +=back + +When running from B<systemd>, invoke B<systemctl daemon-reload> after editing +C<start.conf>. + +The C<pg_ctl.conf> file in the cluster configuration directory can contain +additional options passed to B<pg_ctl> of that cluster. + +=head1 DEFAULT VALUES + +Some default values used by B<pg_createcluster> can be modified in +C</etc/postgresql-common/createcluster.conf>. Occurrences of B<%v> are replaced +by the major version number, and B<%c> by the cluster name.

It +essentially wraps the L<pg_ctl(1)> command. It determines the cluster version +and data path and calls the right version of B<pg_ctl> with appropriate +configuration parameters and paths. + +You have to start this program as the user who owns the database cluster or as +root. + +To ease integration with B<systemd> operation, the alternative syntax +"B<pg_ctlcluster> I<version>B<->I<cluster> I<action>" is also supported. + +=head1 ACTIONS + +=over 4 + +=item B<start> + +A log file for this specific cluster is created if it does not exist yet (by +default, +C</var/log/postgresql/postgresql->I<cluster-version>C<->I<cluster-name>C<.log>), +and a PostgreSQL server process (L<postgres(1)>) is started on it. Exits with +0 on success, with 2 if the server is already running, and with 1 on other +failure conditions. + +=item B<stop> + +Stops the L<postgres(1)> server of the given cluster.

If +that does not work, shutdown is attempted again in "immediate" mode, which can +leave the cluster in an inconsistent state and thus will lead to a recovery run +at the next start. If this still does not help, the B<postgres> process is +killed. Exits with 0 on success, with 2 if the server is not running, and with +1 on other failure conditions. This mode should only be used when the machine +is about to be shut down. + +=item B<-m>|B<--mode> [B<smart>|B<fast>|B<immediate>] + +Shutdown mode to use for B<stop> and B<restart> actions, default is B<fast>. +See pg_ctl(1) for documentation. + +=item B<--foreground> + +Start B<postgres> in foreground, without daemonizing via B<pg_ctl>. + +=item B<--stdlog> + +When B<--foreground> is in use, redirect stderr to the standard logfile in +C</var/log/postgresql/>.

The +configuration files of the old version are copied to the new cluster and +adjusted for the new version. The new cluster is set up to use data page +checksums if the old cluster uses them. + +The cluster of the old version will be configured to use a previously unused +port since the upgraded one will use the original port. The old cluster is not +automatically removed. After upgrading, please verify that the new cluster +indeed works as expected; if so, you should remove the old cluster with +L<pg_dropcluster(8)>. Please note that the old cluster is set to "manual" +startup mode, in order to avoid inadvertently changing it; this means that it +will not be started automatically on system boot, and you have to use +L<pg_ctlcluster(8)> to start/stop it. See section "STARTUP CONTROL" in +L<pg_createcluster(8)> for details. + +The I<newdatadir> argument can be used to specify a non-default data directory +of the upgraded cluster. It is passed to B<pg_createcluster>. If not specified, +this defaults to /var/lib/postgresql/I<newversion>/I<name>. + +=head1 OPTIONS + +=over 4 + +=item B<-v> I<newversion> + +Set the version to upgrade to (default: latest available). + +=item B<--logfile> I<filel> + +Set a custom log file path for the upgraded database cluster. + +=item B<--locale=>I<locale> + +Set the default locale for the upgraded database cluster. If this option is not +specified, the locale is inherited from the old cluster. + +When upgrading to PostgreSQL 11 or newer, this option no longer allows to +switch the encoding of individual databases. (L<pg_dumpall(1)> was changed to +retain database encodings.) + +=item B<--lc-collate=>I<locale> + +=item B<--lc-ctype=>I<locale> + +=item B<--lc-messages=>I<locale> + +=item B<--lc-monetary=>I<locale> + +=item B<--lc-numeric=>I<locale> + +=item B<--lc-time=>I<locale> + +Like B<--locale>, but only sets the locale in the specified category. + +=item B<-m>, B<--method=>dump|upgrade + +Specify the upgrade method.

The default is +"dump". + +=item B<-k>, B<--link> + +In pg_upgrade mode, use hard links instead of copying files to the new +cluster. This option is merely passed on to pg_upgrade. See +L<pg_upgrade(1)> for details. + +=item B<-j>, B<--jobs> + +In pg_upgrade mode, number of simultaneous processes to use. This +option is merely passed on to pg_upgrade. See L<pg_upgrade(1)> +for details. + +=item B<--rename=>I<new cluster name> + +Use a different name for the upgraded cluster. + +=item B<--old-bindir=>I<directory> + +Passed to B<pg_upgrade>. + +=item B<--maintenance-db=>I<database> + +Database to connect to for maintenance queries. The default is B<template1>. + +=item B<--[no-]start> + +Start the new database cluster after upgrading. The default is to start the new +cluster if the old cluster was running, or if upgrade hook scripts are present. + +=back + +=head1 HOOK SCRIPTS + +Some PostgreSQL extensions like PostGIS need metadata in auxiliary tables which +must not be upgraded from the old version, but rather initialized for the new +version before copying the table data. For this purpose, extensions (as well as +administrators, of course) can drop upgrade hook scripts into +C</etc/postgresql-common/pg_upgradecluster.d/>.

(Note the + missing trailing slash, the idea is that the version number can just be + appended to the path, e.g. /usr/lib/postgresql/9.4/bin becomes + /usr/pgsql-9.4/bin.) + +* The various symlinks for frontend programs in /usr/bin like psql are not + direct symlinks to pg_wrapper, but are added as high-priority alternatives to + the alternatives symlinks set up by the PostgreSQL RPM packages. + +* SSL is disabled by default because there is no easily available snakeoil + certificate.
