Many of the modules have regression tests, which can be executed by

running:

<screen>

<userinput>gmake check</userinput>

</screen>

before installation or

<screen>

<userinput>gmake installcheck</userinput>

</screen>

once you have a <productname>PostgreSQL</> server running. (Note that

<literal>gmake check</> is not supported; you must have an operational

database server to perform these tests, and you must have built and

installed the module(s) to be tested.)

once you have a <productname>PostgreSQL</> server running.
