Fwd: resetting superuser password

I have lost the superuser (user postgres) password, but I still have the un=
ix root password. Is there anything I can do to reset the postgres user's =
password (short of reinstalling Postgres)?

Obviously, I can su to unix user postgres, but this does not seem to advanc=
e my cause, as doing "psql -U postgres" still prompts me for a password, wh=
ich is not the same as the unix postgres user's password.

OS: RedHat 9

Help!

Thanks,
Marc

Edit pg_hba.conf and set the auth method to trust. Then reload postgresql=
..
This will stop PostgreSQL from asking you a password.

Hi,

which version of postgres do you have? Put this temporarly into
the /var/lib/pgsql/data/pg_hba.conf:

if postgres 8:
local all postgres 127.0.0.1/32 trust

if postgres 7:
local all trust

then connect to template1...:
psql -U postgres -d template1

....and set your password:
alter user postgres with encrypted password 'blablubb';

i hope this works.

regards,

martin

Re: Fwd: resetting superuser password

Thanks to all who replied, and all apologies for the multiple posting
(my fault).

The solution (in postgres 8.0.1):

Edit data/pg_hba.conf to contain the line:

local all postgres trust

Then su to unix user postgres and restart postges with:

> bin/pg_ctl restart -D /usr/local/pgsql/data -m fast

and finally, login to postgres with:

> psql -U postgres -d template1

and do

alter user postgres with encrypted password 'newpass';

Remove the line added to pg_hba.conf, and restart postgres again!
I'm a happy (and very relieved) camper.

Marc
