Question

Several days ago I install postgesql 9.2 version on my local computer. (OS windows 7)

Now I forgot my password and I can not login in pgAdmin.

How to change pos

Answer 1

Run your psql executable file and login into your database using your old password, use the following command to login:

 .\psql.exe -U postgres

Then use

ALTER USER <user_name> WITH PASSWORD <'new_password'>

Answer 2

In windows postgres stores password for automatic login at following path (only if you would have selected password save option while installation)

C:\Users\USERNAME\AppData\Roaming\postgresql\pgpass.conf

you can open this file in a text editor and see your password.

Answer 3

In the pg_hba.conf file, change (temporarily) all METHOD with trust. EG :

host    all             all             ::1/128                 trust

instead of :

host    all             all             ::1/128                 md5

You can find where the pg_hba.conf is located by typing in a psql command line:

SHOW hba_file;

Answer 4

Edit pg_hba.conf to allow you to connect without a password. Then use ALTER USER to reset the password. Then change pg_hba.conf back again.

For the documentation on pg_hba.conf, see here:

Answer 5

Below steps helped me to reset the password-

1. Go to pg_hba.conf file at path e.g. C:\Program Files\PostgreSQL\10\data and add below line at the end,

   host all postgres 127.0.0.1/32 trust
   

2. Restart the PostgreSQL service from services control panel (start -> run -> services.msc)

3. Connect using PgAdmin or any software that you prefer and run query,

   ALTER USER postgres PASSWORD 'postgres'
   

4. Remove the line that you added in step 1.

5. Restart PostgreSQL.
