I don't think that I've seen SearchCatCache() quite this high on any of the profiling I've done, but then again I don't tend to profile the same things you do, so maybe that's not surprising. I think the interesting question is probably "where are all those calls coming from?" and "can we optimize any of them away?" rather than "how do we make SearchCatCache() run faster?". I would be willing to bet money that the latter is largely an exercise in futility. -- Robert Haas EnterpriseDB: http://www.enterprisedb.com The Enterprise PostgreSQL Company
