How to access the postgreSQL DB of Application Manager

How to access the postgreSQL DB of Application Manager

I have requirement to gather how many transaction counts of say login, search etc are used in last 6 months to year regardless of whether it was slow or not.

I had not seen any option in Manage Engine Application Manager.

So i wanted to access the postgreSql and get data myself.

Please advice.

Thank you all folks
