H.3. Procedural Languages

PostgreSQL™ includes several procedural languages with the base distribution: PL/pgSQL, PL/Tcl, PL/Perl, and PL/Python.

In addition, there are a number of procedural languages that are developed and maintained outside the core PostgreSQL™ distribution. Table H.2 lists some of these packages. Note that some of these projects might not be released under the same license as PostgreSQL™. For more information on each procedural language, including licensing information, refer to its website and documentation.
