Fixing msfconsole slow search - Database not connected or cache not built

Metasploit often throws an error that its database cache is not yet ready and will continue using slow search.

To fix this issue, ensure postgresql is started and check status

$ sudo service postgresql start
$ sudo service postgresql status 

Re-initilaize msfconsole and rebuild the database cache

$ sudo  msfdb init
msf> db_rebuild_cache
msf> db_status

The search should be ready now

If this doesnt work, try the following command to re-establishing the database connection to complete the trick

msf > db_connect -y /usr/share/metasploit-framework/config/database.yml
