++[Code contributed by Mathieu Arnold]
++
++We've written code to add a pgsql map type. It utilizes the pgsql
++client library, which can be obtained from:
++
++ http://www.postgresql.org/
++
++In order to build postfix with pgsql map support, you will need to add
++-DHAS_PGSQL and -I for the directory containing the postgres headers, and
++the libpq library (and libcrypt) to AUXLIBS, for example:
++
++make -f Makefile.init makefiles \
++ 'CCARGS=-DHAS_PGSQL -I/some/where/include/postgresql' \
++ 'AUXLIBS=/some/where/lib/postgres/libpq.a -lcrypt'
++
++then, just run 'make'.
++
++Postfix installations which may benefit from using pgsql map types
++include sites that have a need for instantaneous updates of
++forwarding, and sites that may benefit from having mail exchangers
++reference a networked database, possibly working in conjunction with a
++customer database of sorts.
++
++Once postfix is built with pgsql support, you can specify a map type
++in main.cf like this:
++
++alias_maps = pgsql:/etc/postfix/pgsql-aliases.cf
++
++The file /etc/postfix/pgsql-aliases.cf specifies lots of information
++telling postfix how to reference the postgresql database. An example
++postgresql map config file follows:
++
++#
++# postgresql config file for alias lookups on postfix
++# comments are ok.
++#
++
++# the user name and password to log into the pgsql server
++user = someone
++password = some_passwordd
++
++# the database name on the servers
++dbname = customer_database
++
++# the table name
++table = mxaliases
++
++#
++select_field = forw_addr
++where_field = alias
++
++# you may specify additional_conditions here
++additional_conditions = and status = 'paid'
++
++# the above variables will result in a query of
++# the form:
++# select forw_addr from mxaliases where alias = '$lookup' and status = 'paid'
++# ($lookup is escaped so if it contains single quotes or other odd
++# characters, it will not cause a parse error in the sql).
++#
++# the hosts that postfix will try to connect to
++# and query from (in the order listed)
++hosts = host1.some.domain host2.some.domain
++
++# end postgresql config file
++
++Some notes:
++
++This configuration interface setup allows for multiple postgresql
++databases: you can use one for a virtual table, one for an access
++table, and one for an aliases table if you want.
++
++Since sites that have a need for multiple mail exchangers may enjoy
++the convenience of using a networked mailer database, but do not want
++to introduce a single point of failure to their system, we've included
++the ability to have postfix reference multiple hosts for access to a
++single pgsql map. This will work if sites set up mirrored pgsql
++databases on two or more hosts. Whenever queries fail with an error
++at one host, the rest of the hosts will be tried in order. Each host
++that is in an error state will undergo a reconnection attempt every so
++often, and if no pgsql server hosts are reachable, then mail will be
++deferred until atleast one of those hosts is reachable.
++
++Performance of postfix with pgsql has not been thoroughly tested,
++however, we have found it to be stable. Busy mail servers using pgsql
++maps will generate lots of concurrent pgsql clients, so the pgsql
++server(s) should be run with this fact in mind. Any further
++performance information, in addition to any feedback is most welcome.

++/*++
++/* NAME
++/* dict_pgsql 3
++/* SUMMARY
++/* dictionary manager interface to db files
++/* SYNOPSIS
++/* #include <dict.h>
++/* #include <dict_pgsql.h>
++/*
++/* DICT *dict_pgsql_open(name, dummy, unused_dict_flags)
++/* const char *name;
++/* int dummy;
++/* int unused_dict_flags;
++/* DESCRIPTION
++/* dict_pgsql_open() creates a dictionary of type 'pg'. This
++/* dictionary is an interface for the postfix key->value mappings
++/* to pgsql. The result is a pointer to the installed dictionary,
++/* or a null pointer in case of problems.
++/*
++/* The pgsql dictionary can manage multiple connections to different
++/* sql servers on different hosts. It assumes that the underlying data
++/* on each host is identical (mirrored) and maintains one connection
++/* at any given time. If any connection fails, any other available
++/* ones will be opened and used. The intent of this feature is to eliminate
++/* a single point of failure for mail systems that would otherwise rely
++/* on a single pgsql server.
++/*
++/* Arguments:
++/* .IP name
++/* The path of the PostgreSQL configuration file. The file encodes a number of
++/* pieces of information: username, password, databasename, table,
++/* select_field, where_field, and hosts. For example, if you want the map to
++/* reference databases of the name "your_db" and execute a query like this:
++/* select forw_addr from aliases where alias like '<some username>' against
++/* any database called "vmailer_info" located on hosts host1.some.domain and
++/* host2.some.domain, logging in as user "vmailer" and password "passwd" then
++/* the configuration file should read:
++/*
++/* user = vmailer
++/* password = passwd
++/* DBname = vmailer_info
++/* table = aliases
++/* select_field = forw_addr
++/* where_field = alias
++/* hosts = host1.some.domain host2.some.domain
++/*
++/* .IP other_name
++/* reference for outside use.
++/* .IP unusued_flags
++/* unused flags
