Couple of examples: http://archives.postgresql.org/pgsql-general/2002-10/msg00022.php and http://archives.postgresql.org/pgsql-general/2002-12/msg00426.php There is a recent example in Elein Mustain's "General Bits" column: http://archives.postgresql.org/pgsql-general/2002-12/msg00426.php The contrib table functions are all C based. You can download them directly from cvs -- for instructions see: http://developer.postgresql.org/TODO/docs/cvs.html#ANONCVS or just to browse see: http://developer.postgresql.org/cvsweb.cgi/pgsql-server/contrib/dblink/ and http://developer.postgresql.org/cvsweb.cgi/pgsql-server/contrib/tablefunc/ And finally, in the manual see: general -> http://developer.postgresql.org/docs/postgres/xfunc-tablefunctions.html sql -> http://developer.postgresql.org/docs/postgres/xfunc-sql.html (sec 9.2.4) C -> http://developer.postgresql.org/docs/postgres/xfunc-c.html (sec 9.5.6) plpgsql -> http://developer.postgresql.org/docs/postgres/plpgsql-control-structures.html usage -> http://developer.postgresql.org/docs/postgres/sql-select.html (from_item, inputs, from clause, usage) Possibly others, but that's all I can think of.
