Hi, Using the same debugging hack^Wpatch (0001) as in the matview patch (0002) an hour or so ago I noticed that INSERT INTO view WITH CHECK doesn't lock the underlying relations properly.
I've attached a sort-of-working (0003) hack but I really doubt it's the correct approach, I don't really know enough about that area of the code. This looks like something that needs to be fixed. Also attached is 0004 which just adds a heap_lock() around a newly created temporary table in the matview code which shouldn't be required for correctness but gives warm and fuzzy feelings as well as less debugging noise. Wouldn't it be a good idea to tack such WARNINGs (in a proper and clean form) to index_open (checking the underlying relation is locked), relation_open(..., NoLock) (checking the relation has previously been locked) and maybe RelationIdGetRelation() when cassert is enabled? ISTM we frequently had bugs around this.
