How to connect SDP to stand-alone PostgreSQL

How to connect SDP to stand-alone PostgreSQL

Hi,
I installed PostgreSQL v12 (port 12000) on same server that SDP installed and change DB server configuration to new PostgreSQL instance, but when I execute run.bat, show me below error:
  1. Unable to start Postgres server on port 12000, since another instance of postgre
    s is running in this port.



    Problem while Starting Server
    System halted
    Press any key to continue . . .

What should I do?
