Re: Special-case executor expression steps for common combinations - Mailing list pgsql-hackers

I have bench marked the two patches now and failed to measure any 
speedup or slowdown from the first patch (removing return) but I think 
it is a good idea anyway.

For the second patch (optimize strict) I managed to measure a ~1% speed 
up for the following query "SELECT sum(x + y + 1) FROM t;" over one 
million rows.

I would say both patches are ready for committer modulo my proposed 
style fixes.
