Right -- an extension is not considered to live within a schema, they are database-global. The objects might live in a particular schema (if it is "relocatable"), and there's support to move those to a different schema, but this doesn't affect the extension itself. -- Álvaro Herrera http://www.2ndQuadrant.com/ PostgreSQL Development, 24x7 Support, Training & Services -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
