Hi,
I was checking the GRANT on pg_subscription and noticed that the command is not
correct. There is a comment that says "All columns of pg_subscription except
subconninfo are readable". However, there are columns that aren't included: oid
and subsynccommit. It seems an oversight in the commits 6f236e1eb8c and
887227a1cc8.
There are monitoring tools and data collectors that aren't using a
superuser to read catalog information (I usually recommend using pg_monitor).
Hence, you cannot join pg_subscription with relations such as
pg_subscription_rel or pg_stat_subscription because column oid has no
column-level privilege. I'm attaching a patch to fix it (indeed, 2 patches
because of additional columns for v14). We should add instructions in the minor
version release notes too.
This issue was reported by Israel Barth.
