Thought I was going mad - I’m running local Postgres from WSL using Podman and definitely exposing port
5432 but IntelliJ (DataGrip) won’t connect:
The error is:
Connection to localhost:5432 refused. Check that the hostname and port are correct and that the postmaster is accepting TCP/IP connections.
To confirm the port is exposed to the master host I can sysinternals TCPView:
5432 is listening to connections, but not on
localhost - it’s using IPv6 only. In IPv6 terms localhost is called
::1 so changing to that works fine:
