These types provide a 4-byte datatype for storing real-world second precision timestamps, as occur in many log files. Forcing people to switch to timestamp or timestamptz will incur a 4 byte per row penalty. In my own builds, I have changed the epoch on these so they won't wrap until sometime after 2100 C.E. I see little point in switching to an 8-byte millisecond precision datatype when a perfectly good 4-byte second precision datatype already serves the purpose. That said, I am fully aware that these are deprecated and expect you will remove them, at which time I'll have to keep them in my tree and politely refuse to merge in your change which removes them. mark -- Sent via pgsql-hackers mailing list (firstname.lastname@example.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
