Re: serial column



It's the behavior I expect - but the gaps aren't acceptable.

The SERIAL is always sequential. SERIAL internally creates a SEQUENCE
and *binds* it to your table. even if you delete a record and insert a
new one , the sequence will continue to increment. however there will be
gaps between the values.

Isn't this the behavior you expect?

But the only way of insuring that the serial starts at 1 and is sequential
is to recreate the table.

I've tried creating and dropping the table but this generates other issues
which I haven't been able to resolve.
