Updates failing yet saying they succeeded.

It looks like it's doing exactly what you are asking. Observe:

Okay, updating RA2-1002998...

} UPDATE 1

This time, updating on RA2-1042998...

} autosupply_co_jp=> select fob_price from vehicle where chassis_number =

} fob_price
} -----------
} 420000
} (1 row)

...and selecting on the same, RA2-1042998.

} WTF is up with that?

It didn't work the first time because you were not selecting the same thing
you'd updated. Pilot error.

This is a tad hard to believe. Can you supply a complete example that
would let someone else reproduce the problem? (No, I don't think that
any random update/select sequence will act that way.)

Is that a copy/paste error that the chassis numbers don't match in those
first statements?

I'm sorry. My bad. It appears I just made a typo... Nevermind.

I trust that you did a direct copy-n-paste, and that your first example is
intended to show an update that _says_ it updated (but didn't), and your
second example is to show an updated that did succeed?

If my assumptions are correct, then it looks like you don't really have any
problems (with postgres). You updated one chassis_number, but did a select
for a different chassis_number in your first query.

Thanks to everyone who answered my email so quickly. Yet more proof
that OpenSource/Free Software support is better than commercial
software.

T'was my bad not PgSQL's fault. I'm the fool who can't type correctly
and entered incorrect chassis numbers confusing myself and accusing
PgSQL of doing something wrong.
