<p> <span class="productname">PostgreSQL</span> allows user-defined functions
to be written in other languages besides SQL and C. These other
languages are generically called <em class="firstterm">procedural
languages</em> (<acronym class="acronym">PL</acronym>s).
Procedural languages aren't built into the
<span class="productname">PostgreSQL</span> server; they are offered
by loadable modules.
See <a href="xplang.html" title="Chapter35.Procedural Languages">Chapter35, <i>Procedural Languages</i></a> and following chapters for more
information.
