Yes, the grammar needs to be common. I posted a proposed grammar in
https://www.postgresql.org/message-id/202109241325.eag5g6mpvoup%40alvherre.pgsql
(this thread) which should serve both. I forgot to test the addition of
a WHERE clause for row filtering, though, and I didn't think to look at
adding SEQUENCE support either.
(I'm not sure what's going to be the proposal regarding FOR ALL TABLES
IN SCHEMA for sequences. Are we going to have "FOR ALL SEQUENCES IN
SCHEMA" and "FOR ALL TABLES AND SEQUENCES IN SCHEMA"?)
