I disagree. I think Amit has got the right semantics -- it gives you everything rooted at the partition you name, relative to that root. We could have another function which, given the OID of a partition, returns the topmost parent (or the immediate parent), but I think that if you say "tell me all the partitions of X", it should just tell you about stuff that's under X, regardless of what's over X. -- Robert Haas EnterpriseDB: http://www.enterprisedb.com The Enterprise PostgreSQL Company
