Tom Lane	835bb975d8	Restructure building of join relation targetlists so that a join plan ... node emits only those vars that are actually needed above it in the plan tree. (There were comments in the code suggesting that this was done at some point in the dim past, but for a long time we have just made join nodes emit everything that either input emitted.) Aside from being marginally more efficient, this fixes the problem noted by Peter Eisentraut where a join above an IN-implemented-as-join might fail, because the subplan targetlist constructed in the latter case didn't meet the expectation of including everything. Along the way, fix some places that were O(N^2) in the targetlist length. This is not all the trouble spots for wide queries by any means, but it's a step forward.	2003-06-29 23:05:05 +00:00
Tom Lane	c15a4c2aef	Replace planner's representation of relation sets, per pghackers discussion. ... Instead of Lists of integers, we now store variable-length bitmap sets. This should be faster as well as less error-prone.	2003-02-08 20:20:55 +00:00
