If this were likely to be a 15 line patch, I'd think differently. I'm even more worried about the possible reliability problems (ie introduction of bugs, which are likely to be of the data-eating variety) that such changes are likely to incur. So I tend to agree with Andres that this is probably not a good idea. regards, tom lane -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
