Bug reference:      1051
Logged by:          Jari Aalto

Email address:      jari(dot)aalto(at)poboxes(dot)com

PostgreSQL version: 7.4

Operating system:   W2k SP4 / Cygwin

Description:        Cannot remove groups

Details: 

It is impossible to give details how this error
is triggered, because I do not know enough details
of PG's internals. I happened to crete databases, user, groups and then 
deleting them in random order and now the groups are totally inaccessible in 
all ways. 


The problem is that the admin files say that I have 
groups. But they cannot be removed. And because
they cannot be removed or recreated, I cannot
grant anything to groups.

I tried to install all from  fresh with:

root(at)w2kpicasso:/usr/share/postgresql# rm -rf data/                          
   root(at)w2kpicasso:/usr/share/postgresql# LC_ALL=C initdb -D 
/usr/share/postgresql/data 



But that dind't affect the groups or users. This was verified by running 
select from pg_group and pg_users immedately after total recreation. 

See logs below. Please let me know how to preceed
and help to find more details for you.

The files belonging to this database system will be owned by user "root".
This user must also own the server process.
