The RPM port changes little in +the original code, and even uses many files from the debian/ directory for +building the packages. + +No separate PostgreSQL client/server packages are provided; the port is backed +by the PGDG RPM packages from yum.postgresql.org. + +The filesystem layout is unchanged, /etc/postgresql, /etc/postgresql-common, +and /var/lib/postgresql are used as before. + +Differences between the Debian and RedHat operating modes are: + +* /var/run/postgresql/ is still used for external pid files, but the default + unix socket directory is /tmp, to match the RPM packages' default. + +* The postgres system user home is /var/lib/pgsql. + +* The binroot is changed from /usr/lib/postgresql/ to /usr/pgsql-. (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. Proper certificates can be configured in createcluster.conf. + +* No attempt is made to setup OOM killer protection for the postmaster process. + +* On Debian, the /etc/init.d/postgresql init script skips versions that have + their own /etc/init.d/postgresql-x.y init script, mostly for compatibility + with legacy packages before the advent of the postgresql-common framework. + The RPM packages provide /etc/init.d/postgresql-x.y scripts, which are + ignored by /etc/init.d/postgresql. The postgresql-x.y scripts will not do + anything as long as the user does not use them to create clusters in + /var/lib/pgsql. (In which case they continue to work as if postgresql-common + was not present.) + +* Debian's pre/postinst/rm maintainer scripts are not used. Mostly this means + there is no automatic integration of tsearch with system-provided + dictionaries. + +The postgresql-common testsuite is supported if perl-Test-Simple and +perl-Time-HiRes are installed. + + -- Christoph Berg <christoph.berg@credativ.de> Thu, 26 Jun 2014 16:59:47 +0200 |
