created with a too-low maximum value (see help on CREATE SEQUENCE for
options); the user now wants to raise it.

Seq Scan on states (cost=0.00..1171.51 rows=44627 width=20)
Filter: (state = 'ok'::character varying)
(2 rows)
Looks right to me: index scan for the less-common option, seqscan for
the most common. Why don't you think this, as a btree, will work for
you?

to no-TZ], it will keep
track of just HMS. Or put in other values for 0 for more granularity on
seconds.
Of course, you can always store the specific time and select it out
w/less resolution (using the time/date functions). In some cases, this
might be a better solution.

whereas 'Cat' + 'Dog' = ASCII result of this (not what you want)
. IIf() is a nonstandard Microsoft function used in Access. SQL databases
use CASE. See the docs for examples on CASE.

TIP 4
The default security setup in PG is to allow all connections from localhost,
w/o password. This should be changed. You'll find this in your $PGDATA
directory, in the file pg_hba.conf.

In any event, inserting then using currval() is the standard practice
around here, and it works great
by dropping indexes and
triggers on B.TheTable, doing the INSERTs, then re-adding these.

On the really QD, can you split (man split) your ID
file into a few pieces, PG COPY this to temp tables (say 10 or 20), and
use these smaller tables for your updates?

the ilike function does?
CREATE INDEX lname_lower ON person ( lower(lname) );
(above step is optional, but helps performance)
SELECT * FROM person WHERE lower(lname) = 'defelice'
should be faster than ILIKE.

TIP 2: you can get off all lists at once
don't have a 7.0 db running anywhere to
see that this fails under 7.0.
BTW, I was being far to simplistic in suggesting that
you should pipe pg_dump to sed to psql. As was pointed out,
redirect pg_dump to a file, sed/perl/edit that, then redirect from that to
psql.
HTH,

the ones I offered. D'oh!
Thanks for posting it to the list.

How can I do in order to have one ?
Look at the pg_hba.conf file (normally in $PGDATA directory).
You'll want to change the 'trust' to 'password' for local users.

Normally, you want to up your debug level in pg_options.
Can you tell us more specifically what you've tried to do?
