[SQL] Re: Normalization is always good?

[SQL] serial type; race conditions

Hi, I'm using serial fields to generate IDs for almost all object in my database. I insert an empty row, get the CURRVAL() of the sequence and then update to that value. I had understood (and now, I can't find the reference to back this up) that serial is implemented in such a way that race con

[SQL] Need to do an ALTER TABLE.

Hi, I've got a live database running PSQL 7.0.3. I need to do a couple of changes to some of the table schema's but need to preserve the data that currently exists in the tables. I've used pg_dump to make backups and have verified that I can indeed restore into an empty database from those back
