Hi all;
I have a function which moves a table from one schema to another by
updating the relnamespace field of pg_class:
CREATE OR REPLACE FUNCTION move_relation(VARCHAR, VARCHAR, VARCHAR)
RETURNS BOOL
AS '
-- $1 is the table name
-- $2 is the source schema
-- $3 is the destination schema
--
UPDATE pg_catalog.pg_class
SET relnamespace = (SELECT oid FROM pg_catalog.pg_namespace
WHERE nspname = $3)
WHERE relnamespace = (SELECT oid FROM pg_catalog.pg_namespace
WHERE nspname = $2)
AND relname = $1;
UPDATE pg_catalog.pg_type
SET typnamespace = (SELECT oid FROM pg_catalog.pg_namespace
WHERE nspname = $3)
WHERE typnamespace = (SELECT oid FROM pg_catalog.pg_namespace
WHERE nspname = $2)
AND typname = $1;
SELECT TRUE;
' LANGUAGE SQL;
Am I missing anything? I have already had a few problems that led me to discover
that I needed to put in the second update query. Just figured I would check.
Best Wishes,
Chris Travers

pg_constraint entries related to the table.
Also you need to recurse for each index of the table.
