Error connecting to Citus master


Hi, I am getting the following error when trying to connect to citus master with psql commands.

```
psql -h localhost -U postgres -p 5500
psql: error: server closed the connection unexpectedly
This probably means the server terminated abnormally
before or while processing the request.
```

But I am able to connect without error with the following command.

```
docker exec -it citus_master psql -U postgres
psql (13.2 (Debian 13.2-1.pgdg100+1))
Type "help" for help.

postgres=#
```
I need to connect to citus with psql commands as it needs to be connected via Node Js application.
Or is there another way to do this?
Thank you.
