What are the steps to connect to the vRealize Operations Manager databases for debugging?

Database passwords are stored in `/var/vmware/vpostgres/11/.pgpass`. At least two PostgreSQL instances run on ports 5432 and 5433. For example, connect to the vcopsdb on port 5432 using: `/opt/vmware/vpostgres/11/bin/psql -h localhost -p 5432 -d vcopsdb -U vcops` and then enter the password. This setup is similar to other VMware product debugging environments, such as vRealize Log Insight Vulnerability Debugging Environment Setup.
