Choose the language appropriate to the task.
Shells are very heavy users of process forking/execing.
Using a language like Perl, C, C++, Java may give a dramatic improvement because they are not continually starting new processes to do tiny tasks.

drop_language
DROP
LANGUAGE(7) PostgreSQL 9.2.7 Documentation DROP LANGUAGE(7)
NAME
DROP_LANGUAGE - remove a procedural language
SYNOPSIS
DROP [ PROCEDURAL ] LANGUAGE [ IF EXISTS ] name [ CASCADE | RESTRICT ]
DESCRIPTION
DROP LANGUAGE removes the definition of a previously registered procedural language. You must be a superuser or the owner of the language
to use DROP LANGUAGE.
Note
As of PostgreSQL 9.1, most procedural languages have been made into "extensions", and should therefore be removed with DROP EXTENSION
(DROP_EXTENSION(7)) not DROP LANGUAGE.
PARAMETERS
IF EXISTS
Do not throw an error if the language does not exist. A notice is issued in this case.
name
The name of an existing procedural language. For backward compatibility, the name can be enclosed by single quotes.
CASCADE
Automatically drop objects that depend on the language (such as functions in the language).
RESTRICT
Refuse to drop the language if any objects depend on it. This is the default.
EXAMPLES
This command removes the procedural language plsample:
DROP LANGUAGE plsample;
COMPATIBILITY
There is no DROP LANGUAGE statement in the SQL standard.
