Tom,

I have tried this on a copy of my database system.
When the postmaster boots up I get "this database has no tables" in webmin.

I am unable to compile pg_control because my gcc is too recent (RedHat 7.1) so unable to try and get the table data out.

Can you think of any other tool i might try to get the data tables back? The database structure is real simple I just need the table data.

Cheers

Tony

SQL92 says that abutting time intervals don't overlap, if I'm reading
the spec correctly.

For dates, it would seem to me that you want to add 24 hours to the end
of one interval in order to get the behavior you're describing.

I agree, that's pretty bogus. Why not use infinity and -infinity?
(okay, they don't exist as DATE values, but they do exist as
timestamp values).

regards, tom lane
