I have two databases running locally, I am able to connect to both via the psql command line, but when I attempt to connect to the second database, my unit test db, it throws a "Connection to server has been lost" error. I have no issues connecting to the development database via pgAdmin4.
Here is the console output:
$ psql
psql (9.6.4)
Type "help" for help.
admin=# \c development
You are now connected to database "development" as user "admin".
development=# \c test
You are now connected to database "test" as user "admin".
test=#
