I agree that the current patch structure is hard to follow and doesn’t
add much value, since patch001 isn’t aligned with a specific approach.
How about this patch structure:
patch001: Implement EXCEPT syntax and CREATE PUBLICATION changes. This
includes all changes required to correctly populate
pg_publication_tables and pg_publication_rel.
Expectation for patch001:
When this patch is applied on its own, CREATE PUBLICATION command with
the EXCEPT clause should work, and the appropriate entries should
appear in pg_publication_tables/pg_publication_rel with the except
flag set correctly. No publishing expected in this patch.
patch002: Enable publishing and subscription support.
All changes required to make subscriptions work should go here, including:
--table sync and other subscriber-side changes
--pgoutput logic to determine which tables are published
Expectation for patch002:
Changes should be published and replicated correctly to the subscriber.
patch003: pg_dump, tests, documentation, etc.
All of the above changes/patches are intended to support Approach001.
Approach003 has a limitation in that it allows 'only' ROOT table to be
specified in the EXCEPT clause. If tab_root is listed in EXCEPT and a
user later attempts to attach it as a partition of another table
using:
'ALTER TABLE root ATTACH PARTITION tab_root', we would need to block
the ATTACH PARTITION command. Given this, we should first try to
implement Approach001 and evaluate its feasibility. If it turns out to
be impractical,
we can fall back to Approach003 or consider other alternatives. For
now, the Approach003 patch can remain on hold.
thanks
