Thank you: I think this is what I was missing, and what wasn't clear from the proposed doc patch. But then how can pg_dump assume that it's always safe to set extra_float_digits = 3? Why the discrepancy between default behavior and what pg_dump gets? It can't know whether the dump is to be restored into the same system or a different one (and AFAICT, there's not even an option to tweak extra_float_digits there). -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
