About patch 2: applies cleanly independently of the first one, compiles,
"make check" is ok.
There is a "make_parsestate", but no corresponding free. The usual
pattern, although there seems to be a few exception, is to "make" and
"free".
Even if there is some under-the-hood garbage collection, I'd suggest to
add a free after the call to ComputePartitionAttrs.
