Greetings,
I'm getting a big performance problem and I would like to ask you what
would be the reason, but first I need to explain how it happens.
Let's suppose I can't use sequences (it seams impossible but my boss
doesn't like specific database features like this one).
For sequence
I would collect the way that 5-10 of the top databases handle unique id's (sequences) for columns and compare them in a small paper. Show your boss that sequences are fairly standard and he should come around.

Yes, exactly. Its clean,
wouldn't a better situation be ADDING a record that is one higher, and
then doing a select MAX()?
The different triggers could do delete on the old records.
In my case that would not apply, because what I had was a need to keep a
sequence counter for each employee, so I added a column

If sequences could be effectively replaced by standard SQL operations,
we would not have bothered to invent them. Nor would
