Hello list,

I'm getting this error as well.  I'm running XP Pro, with SP2 (RC2).  Until 
just now I had PostgreSQL 7.4.1.  As far as I could tell, everything was 
running fine...then as I was updating some tables I started getting errors 
(sorry I didn't record them).  I had my whole database backed up, so I tried 
to delete the database using "dropdb" so I could reload the backup, but the 
dropdb command just hung there and did nothing...

I tried cleaning out the whole PG data folder, and reinitializing.  It seemed 
okay...I could run "createuser", but it hung again with "createdb".  Next I 
installed PostgreSQL 7.4.3.  I got through the setup okay, and the services 
appear to be running fine, db initialized okay, and I could create new users 
as before, but the postmaster.log still has the same "dup(0)" error, and it 
still hangs if I try to create a database.

Earlier this week I installed the second release of XP SP2 - I suppose that 
could have something to do with it.  Did the others with this error find a 
solution?

Kind regards,
Michael Leahy

AFAICT, no.
