In fakt, it allows users with hyphens, but you have to use quotes: CREATE USER "foo-bar"; DROP USER "foo-bar"; Regards,Mario Weilguni -----Ursprüngliche Nachricht----- Von: pgsql-hackers-owner@postgresql.org [mailto:pgsql-hackers-owner@postgresql.org] Im Auftrag von Devrim GUNDUZ Gesendet: Montag, 13.

AFAIK, you can use whatever you want if you double-quote it. test=# create database "hyphen-test"; LOG: transaction ID wrap limit is 2147484134, limited by database "test" CREATE DATABASE test=# \c hyphen-test You are now connected to database "hyphen-test". Note that this is the SQL command, rather than another command such as the createdb or createuser client apps or psql. For example, \c works without the quotes. Michael Glaesemann grzm myrealbox com
