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
