Greetings again,
I'm still getting problems, could you give me some more info about how can I change pg_shadow? I tried lots of ways and nothing works, because it seens to be unaccessible.
persona=> insert into pg_shadow values('postgres', 26, 't', 't', 't', 't', '', NULL);
ERROR: pg_shadow: Permission denied.
persona=> select * from pg_shadow;
ERROR: pg_shadow: Permission denied.
persona=> select * from pg_user;
ERROR: cache lookup for userid 26 failed
persona=> alter user postgres CREATEUSER;
ERROR: ALTER USER: permission denied
After all that errors, I killed postmaster and started a single postgres process, with -O activated and still nothing.
[postgres(at)bxsgalena postgres]$ postgres -d $PGDATA -O persona
