The connection service file allows libpq connection parameters to be
associated with a single service name. That service name can then be
specified by a libpq connection, and the associated settings will be
used. This allows connection parameters to be modified without requiring
a recompile of the libpq application. The service name can also be
specified using the <envar>PGSERVICE</envar> environment variable.

To use this feature, copy
<filename>share/pg_service.conf.sample</filename> to
<filename>etc/pg_service.conf</filename> and edit the file to add
service names and parameters. This file can be used for client-only
installs too. The file's location can also be specified by the
<envar>PGSYSCONFDIR</envar> environment variable.
