Hackers; I spotted this after doing some owner reassignments and then dropping the old roles.
It looks like using either reassign or alter type owner to, the pg_class entry stays with old rolID. Then if we drop that old role going forward pg_dump complains about invalid owner. See below test case. I did look at releast notes above 9.4 and didn't notice a fix. I observed the problem originally on a 9.1 system here. And the warning is a bit confusing since it says "table" rather than type. FYI Thanks $ cat q \set ON_ERROR_STOP begin; select version(); create role foo; create schema foo; set search_path to foo; prepare foo as select c.relowner, t.typowner from pg_class c join pg_type t on typrelid = c.oid and typname = 'foo'; create type foo as (a int); execute foo; alter type foo owner to foo; execute foo; reassign owned by foo to postgres; drop role foo; execute foo; alter type foo owner to postgres; execute foo; commit; \! pg_dump --schema-only --schema foo >/dev/null \echo '^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^\n\n\n' drop schema foo cascade; $ psql -fq SET BEGIN version ---------------------------------------------------------------------------------------------- PostgreSQL 9.3.4 on x86_64-unknown-linux-gnu, compiled by gcc (Debian 4.7.2-5) 4.7.2, 64-bit (1 row) CREATE ROLE CREATE SCHEMA SET PREPARE CREATE TYPE relowner | typowner ----------+---------- 16387 | 16387 (1 row) ALTER TYPE relowner | typowner ----------+---------- 266324 | 266324 (1 row) REASSIGN OWNED DROP ROLE relowner | typowner ----------+---------- 266324 | 10 (1 row) ALTER TYPE relowner | typowner ----------+---------- 266324 | 10 (1 row) COMMIT pg_dump: WARNING: owner of table "foo" appears to be invalid ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ psql:q:39: NOTICE: drop cascades to type foo DROP SCHEMA $ $ -- Jerry Sievers Postgres DBA/Development Consulting e: postgres.consult...@comcast.net p: 312.241.7800 -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
