Thank you for proposing an impressive improvement so quickly! Yes, I'm in the mood for adopting Amit-san's patch as a base because it's compact and readable, and plus add this patch of yours to complement the partition key function case. But ... * Applying your patch alone produced a compilation error. I'm sorry I mistakenly deleted the compile log, but it said something like "There's a redeclaration of PartKeyContext in partcache.h; the original definition is in partdef.h" * Hmm, this may be too much to expect, but I wonder if we can make the patch more compact...
