patch 002:
Commit msg says:
----------
The command then re-fetches the publication tuple after acquiring the
lock, but does not revalidate the publication relations. This can leave
pg_publication_rel containing a mixture of inclusion and exclusion rows.
Re-run CheckAlterPublication() after acquiring the lock so that the
validation uses the current publication state.
---------
The commit message and the fix are not in sync and thus little
confusing. Commit msg talks about re-validation while patch has
shifted the validation to a later point. The code change looks good
though.
patch003: LGTM
patch004: LGTM
