Well, I'm concerned about the global implications. For instance, I
think making parseInput simply return on malloc failure *without doing
any more* will convert out-of-memory from a core dump into an infinite
loop; which is hardly an improvement. (See PQgetResult for one example
of a place that will loop till it gets something.)
I'd be the first to admit that libpq's error handling isn't very good,
but I think fixing it will take some wholesale rework of the internal
calling conventions, not a few lines of localized patches.
Having said that, though, CVS tip does have some progress on this
matter; it will usually behave reasonably when it runs out of memory for
a query result. If you'd like to pursue the matter, please pull down
CVS tip and see what you can do with it. The patch as given would not
be much use to us anyway because of the changes since 7.3...
