I just tested dropping and recreating the 'public' schema and pg_upgrade worked fine. I think the fix we need for extensions is to change: SELECT binary_upgrade.create_empty_extension('plpgsql', 'pg_catalog', false, '1.0', NULL, NULL, ARRAY[]::pg_catalog.text[]); to SELECT binary_upgrade.create_empty_extension('plpgsql', 'pg_catalog', false, '1.0', NULL, NULL, ARRAY[]::pg_catalog.text[]) WHERE (SELECT COUNT(*) FROM pg_extension WHERE extname = 'plpgsql') = 0; This basically conditionally calls binary_upgrade.create_empty_extension() based on whether the extension already exists in the new cluster. -- Bruce Momjian <br...@momjian.us> http://momjian.us EnterpriseDB http://enterprisedb.com + It's impossible for everything to be true. + -- Sent via pgsql-bugs mailing list (pgsql-bugs@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-bugs
