Can you please elaborate. I am not able to understand what DCL is involved here. According to [1], examples of DCL are GRANT and REVOKE command. > Another approach I have is to push down DCL to only foreign servers > that support 2PC protocol, which is similar to DML push down. > This approach would be more simpler than current idea and is easy to > use by distributed transaction manager. Again, can you please elaborate, how that would be different from the current approach and how does it simplify the code. -- Best Wishes, Ashutosh Bapat EnterpriseDB Corporation The Postgres Database Company -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
