Reset lost PostgreSQL admin password

Problem

The PostgreSQL admin/superuser account password is lost.

If the PostgreSQL admin/superuser account password is lost follow this procedure to reset it.

Create a copy of pg_hba.conf so you can revert to it later
Open pg_hba.conf
Change "md5" to "trust" everywhere
Go to the command line (cmd.exe)
CD into the PostgreSQL bin directory (ex: C:\Program Files\PostgresSQL\9.0\bin)
Enter: psql -U postgres ForayAdams
1. (NOTE: if the admin account isn't postgres user whatever the admin account is named; likewise for the db being ForayAdams)
Enter: ALTER USER postgres WITH ENCRYPTED PASSWORD 'somestrongpassword';
1. (NOTE: again, change postgres if necessary)
Enter: \q
Start PgAdmin III and enter the password just set to make sure it works.
Swap the pg_hba.conf back to the previous version.
