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
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.
pg_hba.conf
For the documentation on pg_hba.conf, see here:
