I know this is only in 7.1, not in earlier versions

No - afraid not. Queries are pre-compiled as I understand it, although
this is possible in pltcl (and plperl I think).

Take a look at http://www.brasileiro.net/postgres/ for some example
plpgsql functions or check http://techdocs.postgresql.org or Bruce's book
at http://www.postgresql.org/docs/awbook.html
If you have a specific example, please post it with the version of PG you
are running.
