These tables are usually in +# \fBdbm\fR or \fBdb\fR format. +# +# Alternatively, lookup tables can be specified as PostgreSQL +# databases. In order to use PostgreSQL lookups, define a +# PostgreSQL source as a lookup table in main.cf, for example: +# .nf +# alias_maps = pgsql:/etc/postfix/pgsql-aliases.cf +# .fi +# +# The file /etc/postfix/pgsql-aliases.cf has the same format as +# the Postfix main.cf file, and can specify the parameters +# described below. +# LIST MEMBERSHIP +# .ad +# .fi +# When using SQL to store lists such as $mynetworks, +# $mydestination, $relay_domains, $local_recipient_maps, +# etc., it is important to understand that the table must +# store each list member as a separate key. The table lookup +# verifies the *existence* of the key. See "Postfix lists +# versus tables" in the DATABASE_README document for a +# discussion. +# +# Do NOT create tables that return the full list of domains +# in $mydestination or $relay_domains etc., or IP addresses +# in $mynetworks. +# +# DO create tables with each matching item as a key and with +# an arbitrary value. With SQL databases it is not uncommon to +# return the key itself or a constant value. +# PGSQL PARAMETERS +# .ad +# .fi +# .IP "\fBhosts\fR" +# The hosts that Postfix will try to connect to and query +# from. Besides a \fBpostgresql://\fR connection URI, this +# setting supports the historical forms \fBunix:/\fIpathname\fR +# for UNIX-domain sockets and \fBinet:\fIhost:port\fR for TCP +# connections, where the \fBunix:\fR and \fBinet:\fR prefixes +# are accepted and ignored for backwards compatibility. +# Examples: +# .nf +# hosts = postgresql://username@example.com/tablename?sslmode=require +# hosts = inet:host1.some.domain inet:host2.some.domain:port +# hosts = host1.some.domain host2.some.domain:port +# hosts = unix:/file/name +# .fi +# +# The hosts are tried in random order. The connections are +# automatically closed after being idle for about 1 minute, +# and are re-opened as necessary. +# .IP "\fBuser, password\fR" +# The user name and password to log into the pgsql server. +# Example: +# .nf +# user = someone +# password = some_password +# .fi +# .IP "\fBdbname\fR" +# The database name on the servers. Example: +# .nf +# dbname = customer_database +# .fi +# .IP "\fBquery\fR" +# The SQL query template used to search the database, where \fB%s\fR +# is a substitute for the address Postfix is trying to resolve, +# e.g. +# .nf +# query = SELECT replacement FROM aliases WHERE mailbox = '%s' +# .fi +# +# This parameter supports the following '%' expansions: +# .RS +# .IP "\fB%%\fR" +# This is replaced by a literal '%' character.

This can significantly +# reduce the query load on the PostgreSQL server. +# .nf +# domain = postfix.org, hash:/etc/postfix/searchdomains +# .fi +# +# It is best not to use SQL to store the domains eligible +# for SQL lookups. +# +# This parameter is available with Postfix 2.2 and later. +# +# NOTE: DO NOT define this parameter for local(8) aliases, +# because the input keys are always unqualified. +# .IP "\fBexpansion_limit (default: 0)\fR" +# A limit on the total number of result elements returned +# (as a comma separated list) by a lookup against the map. +# A setting of zero disables the limit. Lookups fail with a +# temporary error if the limit is exceeded. Setting the +# limit to 1 ensures that lookups do not return multiple +# values. +# OBSOLETE MAIN.CF PARAMETERS +# .ad +# .fi +# For compatibility with other Postfix lookup tables, PostgreSQL +# parameters can also be defined in main.cf. In order to do +# that, specify as PostgreSQL source a name that doesn't begin +# with a slash or a dot. The PostgreSQL parameters will then +# be accessible as the name you've given the source in its +# definition, an underscore, and the name of the parameter. For +# example, if the map is specified as "pgsql:\fIpgsqlname\fR", +# the parameter "hosts" would be defined in main.cf as +# "\fIpgsqlname\fR_hosts". +# +# Note: with this form, the passwords for the PostgreSQL sources +# are written in main.cf, which is normally world-readable. +# Support for this form will be removed in a future Postfix +# version. +# OBSOLETE QUERY INTERFACES +# .ad +# .fi +# This section describes query interfaces that are deprecated +# as of Postfix 2.2. Please migrate to the new \fBquery\fR +# interface as the old interfaces are slated to be phased +# out. +# .IP "\fBselect_function\fR" +# This parameter specifies a database function name. Example: +# .nf +# select_function = my_lookup_user_alias +# .fi +# +# This is equivalent to: +# .nf +# query = SELECT my_lookup_user_alias('%s') +# .fi +# +# This parameter overrides the legacy table-related fields (described +# below). With Postfix versions prior to 2.2, it also overrides the +# \fBquery\fR parameter. Starting with Postfix 2.2, the \fBquery\fR +# parameter has highest precedence, and the \fBselect_function\fR +# parameter is deprecated. +# .PP +# The following parameters (with lower precedence than the +# \fBselect_function\fR interface described above) can be used to +# build the SQL select statement as follows: +# +# .nf +# SELECT [\fBselect_field\fR] +# FROM [\fBtable\fR] +# WHERE [\fBwhere_field\fR] = '%s' +# [\fBadditional_conditions\fR] +# .fi +# +# The specifier %s is replaced with each lookup by the lookup key +# and is escaped so if it contains single quotes or other odd +# characters, it will not cause a parse error, or worse, a security +# problem. +# +# Starting with Postfix 2.2, this interface is obsoleted by the more +# general \fBquery\fR interface described above. If higher precedence +# the \fBquery\fR or \fBselect_function\fR parameters described above +# are defined, the parameters described here are ignored. +# .IP "\fBselect_field\fR" +# The SQL "select" parameter. Example: +# .nf +# \fBselect_field\fR = forw_addr +# .fi +# .IP "\fBtable\fR" +# The SQL "select .. from" table name.
