What do you mean by "more than one value"? Multiple columns
(composite type), multiple rows (set), or both? In any case, the
documentation for each language describes its capabilities.
http://www.postgresql.org/docs/8.1/interactive/server-programming.html
Of the standard languages in PostgreSQL 8.1 you can return sets,
composite types, and sets of composite types with C, SQL, PL/pgSQL,
and PL/Perl but not with PL/Tcl or PL/Python. Third-party languages
with support for sets and composite types include PL/Ruby, PL/php,
PL/R, PL/Java, and possibly others.
