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>,
