Cannot connect to postgres port 5432

[jovezhong]

Describe what's wrong

After starting Timeplus Proton with 5432 port exposed from docker or using bare metal installation, I failed to connect the 5432 Postgres port

psql -h 127.0.0.1 -p 5432
psql: error: connection to server at "127.0.0.1", port 5432 failed: SSL SYSCALL error: EOF detected
connection to server at "127.0.0.1", port 5432 failed: server closed the connection unexpectedly
	This probably means the server terminated abnormally
	before or while processing the request.

The port 5432 is certainly opening for pgsql. Otherwise if I set a different port, the error message is different

psql -h 127.0.0.1 -p 5431
psql: error: connection to server at "127.0.0.1", port 5431 failed: Connection refused
	Is the server running on that host and accepting TCP/IP connections?

Impact
Some users want to use AWS QuickSight to build dashboard for Timeplus. It supports Postgres/MySQL/ClickHouse, but not Timeplus. Considering the long process of adding Timeplus data source to AWS product, we should allow users to use Postgres or MySQL port. This worked before but is broken for a while.

can't wait to see this to be fixed. So we can connect to Timeplus by existing Postgres/MySQL npm packages in node.js environment as well I guess.
