You would like to use a certain language for using postgresql e.g. plpgsql
You can create the language with the command:
CREATE LANGUAGE plpgsql;
You can opt for creating this language in your template database which is used to create new databases. In this case you will always have the language available in new databases.
Createlang is a command line program that is located in the bin folder of your PostgreSQL installation directory.
I you would like to see a list of procedural languages that you already have in PostgreSQL you can use the following select statement:
SELECT * FROM pg_catalog.pg_pltemplate
The output might look like this:
postgres=# SELECT * FROM pg_catalog.pg_pltemplate;
tmplname | tmpltrusted | tmpldbacreate | tmplhandler | tmplvalidator | tmpllibrary | tmplacl
plpgsql | t | t | plpgsql_call_handler | plpgsql_validator | $libdir/plpgsql |
pltcl | t | t | pltcl_call_handler | | $libdir/pltcl |
pltclu | f | f | pltclu_call_handler | | $libdir/pltcl |
plperl | t | t | plperl_call_handler | plperl_validator | $libdir/plperl |
plperlu | f | f | plperl_call_handler | plperl_validator | $libdir/plperl |
plpythonu | f | f | plpython_call_handler | | $libdir/plpython |
and can, probably will, be different on your system.
