How I know whether Postgres is already installed or not on a machine(on

I found that pg_ctl --version could be used or I also tried to check into

with Windows Server 2003 pg_ctl is not recognized (pr

which is the right procedure to clean wal files
after a recovery ??
Hi:
I have a table with many constraints. A user tries to insert a record that
violates many of them. The error message I get back lists the first violation.
How cani I (or can I) get them all?
I'm running 8.3.4 on linux, running through perl/DBI, getting the error message
from $dbh->errstr.

You can't, it stops running the command at the first error.

Zero nulls. It is a primary key.

Huh. The proposed plan should have run in basically zero time then.

Is there a way to temporarily suspend constraint checking for a particular
constraint inside of the transaction, try the insert again, capture the next
violation, then the next, etc... then rollback after all have been collected?

You could do something like
I'm thinking more along the lines of creating a bunch of temp tables, each with
one of the constraints. Then, in a loop, throw the record at each of these
temp tables and collect up the violations.
Exploring now hot to get the pieces I need from the metadata tables to do this.
