Tom Lane 65a7cd0e9c Fix pull_up_sublinks' failure to handle nested pull-up opportunities. ... After finding an EXISTS or ANY sub-select that can be converted to a semi-join or anti-join, we should recurse into the body of the sub-select. This allows cases such as EXISTS-within-EXISTS to be optimized properly. The original coding would leave the lower sub-select as a SubLink, which is no better and often worse than what we can do with a join. Per example from Wayne Conrad. Back-patch to 8.4. There is a related issue in older versions' handling of pull_up_IN_clauses, but they're lame enough anyway about the whole area that it seems not worth the extra work to try to fix.		2011-05-02 15:56:43 -04:00
