For information about writing server-side Perl functions see the
PL/Perl documentation (adjust the link if you're using a version
other than 8.1):

http://www.postgresql.org/docs/8.1/interactive/plperl.html

If the function needs to execute SQL statements in the same backend
in which it's running then see the "Database Access from PL/Perl"
section. If it needs to connect to a different database then you
could use the DBI module.

"Best" is a matter of opinion; others might prefer Ruby, Python,
or something else. Perl is good at text handling, it has a large
number of third-party modules (CPAN), and there's a lot of material
written about it so it's a popular choice.

See the aforementioned PL/Perl documentation. You could also use
PL/Perl just for parsing and use PL/pgSQL for working with the
database.
