I don't know anything about a particular interface to 7.3, but if you're still using 7.3 and are having problems with plans not being properly optimized, I highly recommend upgrading to 8.2. There have been substantial improvements to both the planner in particular and performance in general in the last four releases. Michael Glaesemann grzm seespotcode net
