I have to create users via an ODBC connection, but I get this error:

How about starting new transaction automatically after committing
"create user ..." at backend side if "create user" is the first command
of the transaction ?
So then
begin;

OK, John, I think I have an answer for you. It is not pretty. You
actually got pretty close.
First, increase SHMMAXPGS by 1024 for every additional 4MB of shared

The default setting of 1024 is for a
I've just started using Postgres 6.5.2 and I'm trying to figure out a
way to be able to see the complete 'type' for the 'employee_id' field.
I can't remember which sequence I used in the 'nextval', so I need to
be able to see which one is being used there.
shift= \d employee
Table= employee
A quick and dirty trick, is to make a dump of the schema
of the database (or the table):
postgres# pg_dump -s [-t employee] my-db-name db.dump.schema

Do you have 5 indexes or do you have an index that spans more than one

Sorry for being less than explicit. There are 5 separate indices,
