Tom Lane	b204d10c79	Executor no longer cares about mergejoinop, mergerightorder, mergeleftorder, ... so remove them from MergeJoin node. Hack together a partial solution for commuted mergejoin operators --- yesterday a mergejoin int4 = int8 would crash if the planner decided to commute it, today it works. The planner's representation of mergejoins really needs a rewrite though. Also, further testing of mergejoin ops in opr_sanity regress test.	1999-03-01 00:10:44 +00:00
