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
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 WITH PASSWORD <'new_password'>
