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.
The connection service file can be a per-user service file
at <filename>~/.pg_service.conf</filename> or the location
specified by the environment variable <envar>PGSERVICEFILE</envar>,
or it can be a system-wide file
at <filename>etc/pg_service.conf</filename> or in the directory
specified by the environment variable
<envar>PGSYSCONFDIR</envar>. If service definitions with the same
name exist in the user and the system file, the user file takes
precedence.
