Postgres.app Could not start on port 5432
macos, postgresql
Solution
You my have another instance of postgres running, that is the only application interested in this port. You should use netstat and ps to determine this. Then stop the instance and uninstall it, you mayhave installed enterpiseDb for example, that is what I did.
Problem
I'm using http://postgresapp.com. In the menubar it gives the error " Could not start on port 5432." Similarly if I try to start the server from the terminal, I get: ``` psql: could not connect to server: No such file or directory Is the server running locally and accepting connections on Unix domain socket "/tmp/.s.PGSQL.5432"? ``` I also ran `pg_ctl -D /usr/local/var/postgres -l /usr/local/var/postgres/server.log start` and got the output `server starting` but still get the same errors when connecting to psql.
