Hi All,
I want to create postgresql database and tables using stored functions.
Does postgresql support create statements in stored functions.
Regards,
Manasi

You cannot use CREATE DATABASE from a stored function or in a
multistatements query. But AFAICT, any of the other DDL statements are
available in a stored function (or in a transaction for that matter).

Also I want to query multiple databases from stored functions from one
central database.
for ex :=
CREATE OR REPLACE FUNCTION test () RETURNS AS
$BODY$
SELECT * FROM db2.volume
ORDER BY db2.volume.volumeID
$BODY$
LANGUAGE sql STABLE
COST 100
ROWS 1000;'
I have implemented this thing in mysql but I am not really sure is it
possible in postgresql.

Nope, you can't use the same kind of queries. You need to install dblink
or PL/proxy to get that kind of capacity.
