AlterPublicationOptions() can use stale publication state when the publication is modified concurrently while waiting for the publication lock. In particular, a concurrent ALTER PUBLICATION ... SET ALL TABLES can change puballtables, causing the validation to make decisions based on the old value and leads to assertion failure. Likewise, CheckAlterPublication() could miss a table added concurrently, letting SET ALL TABLES EXCEPT (...) leave pg_publication_rel with a mixture of inclusion and exclusion rows. Fix by acquiring the lock and re-reading the publication tuple in AlterPublication() before either path runs, and by calling CheckAlterPublication() only after that. Also fix 037_except.pl, which left one computed result untested and silently reused a subscription created by an earlier test.
