Help with Metasploit

Hello Guys,

It's been a long time since i started my metasploit framework because of my busy schedules.
I decided to start it up to check some tutorials i found on the web that required metasploit.

Starting Metasploit along with PostgreSQL gave this error:

I scorched the web searching for solutions relating to the error provided
by metasploit but found none.
Since i have never encountered such an error in the framework,
Am posting it here to check if you Guys or anyone has encountered such an error or could anyone suggest any solutions.
Will be sitting by for your response

Thanks for reading .... and < Peace-Out >.
