Forgot Admin Password on Postgres (Windows Installation), can't reset

Question

I have a Windows PostgreSQL installation.

According to some posts, there is no default password set for the \'postgres\' user yet I can\'t connect using an empty pa

Answer 1

Update your pg_hba.conf file to allow for trusted local connections

[root@server] vim pg_hba.conf
>> local all all         trust

then restart your PostgreSQL server

[user@machine] pg_ctl -D C:\PostgreSQL\data restart    (Windows)
[root@server] service postgresql restart            (Linux)

at this point you can connect to your server as postgres user using a local connection without the need to enter a password (omitting the -h parameter when calling the psql command will use a local connection - if you pass -h then this will match the line host all all 0.0.0.0/0 in your pg_hba.conf file)

[root@server] psql -U postgres

You can then alter the postgres user role and set the password to whatever you like using the following command in the psql terminal

[psql] alter role postgres password ;

Once this is done you can restart your PostgreSQL server again

[user@machine] pg_ctl -D C:\PostgreSQL\data restart     (Windows)
[root@server] service postgresql restart             (Linux)

and at this point your password should be changed to the new password
