Um, not done yet (PL/pgSQL table functions). Currently only SQL and C
functions supported. I've had an off-line discussion with Neil, and I
think he is working this item and plans to have it ready for 7.3.
CREATE PROCEDURE is not planned for 7.3 at all (I don't think; see the
CALL foo recent discussion).
It's not clear to me which one is meant by the above. "Dumping the data
ala PL/SQL or T-SQL" could mean either. PL/SQL supports table functions;
T-SQL only supports the CALL foo type capability. See:
http://archives.postgresql.org/pgsql-general/2002-08/msg00602.php
for a description of the difference.
