Ah, nothing like being bug-compatible with a bad implementation.
But I agree, if Oracle ignores the number of 9's there then we
should too.

BTW, this patch adds more NUM_cache_remove() calls.  I'm planning
to commit it that way, unless you're just about to commit your PG_TRY
change?  I agree with doing that, but figured it should be a separate
commit.
