Hi there,

Connection to the postgresql database doesn't work for Metasploit after the last updates.
You can check that from msfconsole by typing : db_status which shows : postgresql selected,no connection
As a temporary solution (I hope ;-)),you can,from the msfconsole,type : db_connect -y /opt/Metasploit/apps/pro/ui/config/database.yml

This is automatically rebuild the cache and get you connected to the database.

Hope that helps someone out there.
