From: ernst.molitor@uni-bonn.de
Hi,
thank you for the latest Postgres95 distribution!
>does the createuser bug still persist, or have
>we finally worked that one out?
As has been indication by Bruce Momjian, the createuser problem was
caused by a bug in flex 2.5.3 (which has been confirmed by Vern
Paxson, the flex maintainer - many thanks to them); the bug will be
fixed in flex 2.5.4. Vern Paxson has been so kind as to supply me with
a patch that will be part of the 2.5.4 release; I'm including it below
in case someone has installed flex 2.5.3 and doesn't want to go
back to 2.5.2...
Regards,
Ernst
