Re: Compound index (pkey) not used when it should be

Thank you. That does in indeed cause the PRIMARY key to be used, and the query performance is as expected.

It seems rather odd that the optimizer would be unable to recognize the applicability of a composite index when evaluating a very simple query where every relevant clause EXACTLY matches the structure of that index.
