This page:
http://www.postgresql.org/docs/postgres/datatype1033.htm
says to use timestamp in preference to datetime. It also says that datetime is
"equivalent to timestamp". Ok, so I'll use timestamp, no prob. But I want to
index that field. In v6.5.3, there is no timestamp_ops, only datetime_ops. In
v7.0b1 the datetime_ops is gone, and there is a timestamp_ops available, which
takes care of my problem. But until I put 7.0 on my production server, I can't
make an index on a timestamp field. My question is, how "equivalent" are these
types? Can I use datetime_ops to index a timestamp field in a v6.5.3 database?
I.e., can I do this:
create table thing ( bleh text, blah timetamp );
create index thing_blah on thing ( blah datetime_ops );
It runs without error, but is it legit? TIA...
