If you installed Composer's metadata store on a server running CentOS or RedHat, complete the configuration steps below. If the server is running Ubuntu, ignore these instructions.

To change authentication for your metadata store to MD5:

1. Edit the pg_hba.conf file.

   sudo vi /var/lib/pgsql/12/data/pg_hba.conf

2. Change METHOD to MD5.

      # IPv4 local connections:   
      host    all             all             127.0.0.1/32            md5
      # IPv6 local connections:
      host    all             all             ::1/128                 md5  

3. Restart PostgreSQL. In CentOS v7 environments, run:

   sudo systemctl restart postgresql-12
