That service name can then be + specified in a libpq connection string, and the associated settings will be + used. This allows connection parameters to be modified without requiring + a recompile of the libpq-using application. The service name can also be + specified using the <code class="envar">PGSERVICE</code> environment variable. + </p><p> + Service names can be defined in either a per-user service file or a + system-wide file. If the same service name exists in both the user + and the system file, the user file takes precedence. + By default, the per-user service file is named + <code class="filename">~/.pg_service.conf</code>. + On Microsoft Windows, it is named + <code class="filename">%APPDATA%\postgresql\.pg_service.conf</code> (where + <code class="filename">%APPDATA%</code> refers to the Application Data subdirectory + in the user's profile). A different file name can be specified by + setting the environment variable <code class="envar">PGSERVICEFILE</code>. + The system-wide file is named <code class="filename">pg_service.conf</code>. + By default it is sought in the <code class="filename">etc</code> directory + of the <span class="productname">PostgreSQL</span> installation + (use <code class="literal">pg_config --sysconfdir</code> to identify this + directory precisely). Another directory, but not a different file + name, can be specified by setting the environment variable + <code class="envar">PGSYSCONFDIR</code>. + </p><p> + Either service 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.

A service file setting + overrides the corresponding environment variable, and in turn can be + overridden by a value given directly in the connection string. + For example, using the above service file, a connection string + <code class="literal">service=mydb port=5434</code> will use + host <code class="literal">somehost</code>, port <code class="literal">5434</code>, + user <code class="literal">admin</code>, and other parameters as set by + environment variables or built-in defaults. + </p></div><div class="navfooter"><hr /><table width="100%" summary="Navigation footer"><tr><td width="40%" align="left"><a accesskey="p" href="libpq-pgpass.html" title="34.16.
