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 <code class="envar">PGSERVICE</code> environment variable. </p><p> The connection service file can be a per-user service file at <code class="filename">~/.pg_service.conf</code> or the location specified by the environment variable <code class="envar">PGSERVICEFILE</code>, or it can be a system-wide file at <code class="filename">`pg_config --sysconfdir`/pg_service.conf</code> or in the directory specified by the environment variable <code class="envar">PGSYSCONFDIR</code>. If service definitions with the same name exist in the user and the system file, the user file takes precedence. </p><p> The file uses an <span class="quote">“<span class="quote">INI file</span>”</span> format where the section name is the service name and the parameters are connection parameters; see <a class="xref" href="libpq-connect.html#LIBPQ-PARAMKEYWORDS" title="34.1.2.
