I read the patch, but only skimmed the earlier discussion about it. In
isolation, I can say that the patch applies cleanly and looks sensible
for what it does (i.e., cache pgprocno to speed up repeated calls to
TransactionIdIsInProgress(somexid)).
In that sense, it's ready for committer, but I don't know if there's a
better/more complete/etc. way to address the original problem.
