I didn't checked code - just I did some performance tests and I am thinking
so performance is very good.
Master's record type has 50% speed of row type in my test. Patched has +/-
same speed.
I see very small slowdown for row type .. about 3% but I think so it is
acceptable - I tested some worst case.
Unfortunately - it breaks and very breaks all plpgsql related extensions -
pldebug, plprofiler, plpgsql_check. On second hand, there are only few
extensions of this kind.
