Looks like we already do that. Then we have remote_conds, local_conds which together should be equivalent to havingQual. Storing all those three doesn't make sense. In future someone may use havingQual instead of remote_conds/local_conds just because its available and then there is risk of these three lists going out of sync. -- Best Wishes, Ashutosh Bapat EnterpriseDB Corporation The Postgres Database Company
