Hm. Could we split it into two functions, pg_get_owned_sequence() and pg_get_identity_sequence()? I see that commit 3012061 [0] added support for identity columns to pg_get_serial_sequence() because folks expected that to work, so maybe that's a good reason to keep them together. If we do elect to keep them combined, I'd be okay with renaming it to pg_get_identity_sequence() along with your other proposed changes.
