This sounds very nice, and this will make PG an even more reliable tool.

Hi all!
I just realized the following behaviour in postgresql: when I violate any
constraint (unique constraint in my case) then the transaction is not usable
anymore. Any other sql command returns a in failed sql transaction error.
I would tend to agree with Tom.
A table is by definition an unordered set of records. Forcing keys to
have meaning of this type implies that there is a relationship between
each record in the set. That's information you should be storing as
part of the record. If order is important, design the

For example if a column contains '2006-02-11 00:30:00-05'

Then using the SERIAL or SEQUENCE won't do you any good.

Thanks for all the help.
I finally used savepoints to get what I want.
However I don't like this very much. I tried a few other databases (hsqldb,

after violating the constraint.
Best regards,
