Yes, I noticed that too. The 'quick/easy' fix that I'm using is
to update sqlTypeCache hashtable which mapped 'oid -> SQLType'.
That was the patch that I sent in. It doesn't break anything 'more'
since a) if its not in cache it puts the value in the sqlTypeCache
hashtable to begin with and b) if it is found in the check, then a
potentially bogus result is returned. (Odds are it won't, since it
currently checks typeOidCache, which maps 'PGType -> oid' instead.
I doubt one would ever have an oid they send into the function, which
would then check the typeOidCache. The oid key wouldn't match the PGType
key to find the oid value. Ugh... my brain hurts... ;-)

Yes. in getOID(String), it uses the typeOidCache correctly. (If the
comments defining the variable typeOidCache are correct.) It maps the
string of the PGType -> the Integer oid.

Yeah, I think it was just a mistake made that didn't give incorrect
results since the item is never cached. (Or, can never be found.)

Thanks, you've given me the info I need on the original discussion.
I think we should see if we can put this fix in before 7.2 is released.
Perchance in the 7.2rc1? Folks? Can someone else verify that our
analysis is correct before the rc1 release?
