Really? I find that slightly surprising, considering that a quick look at master's timestamp.c suggests that the choice to use the in64 representation over the double representation is entirely a case of compile time either/or. There is no apparent fall-back to the double representation available to binaries built without --disable-integer-datetimes. -- Peter Geoghegan http://www.2ndQuadrant.com/ PostgreSQL Development, 24x7 Support, Training and Services -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
