You can use procedural languages like PL/Perl, PL/Python, PL/Tcl,
etc., to do just about anything those languages allow.  Whether
it's appropriate for the database to do certain things is another
matter....

I don't think PostgreSQL 7.4.6 supports trigger functions written
in PL/Perl, but you could write the file-copying function in PL/Perl
and call it from a PL/pgSQL trigger.  Or you could upgrade to 8.0.0,
which does support PL/Perl triggers, or you could write the trigger
in one of the other procedural languages.
