Wrong user mapping for gitlab-geo-psql
If you enter the DB console with gitlab-geo-psql you can't really query FDW tables because user mapping is for gitlab-geo user, not for gitlab-psql. I didn't look into it deeply yet but it's a source of confusion for a long time, see
gitlab-com/migration#329 (comment 69601281), omnibus-gitlab#3468 (closed)
and now it's a customer ticket https://gitlab.com/gitlab-com/geo-customers/issues/11
This is also something related #10348 (closed)
Is this something known?
