I installed in a Ubuntu VM PostgreSQL 13 and it works fine, I can connect from a client SQL GUI. I also installed in the same machine Citus, and it seems to work fine as I can connect locally with psql -p 9700.
But when I try to connect from the client SQL GUI, I get an error saying that couldn't locate the localhost/port.
Any ideas where to look? Also, I don't see 9700 running the command below, is this OK?
postgres@sofubuntu:~$ pg_lsclusters
