killing the postgres service on mac
This ended up working: First, get the pid: $ sudo lsof -i:5432 Password: COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME postgres 73 postgres 4u IPv6 0x8880707cadb2d1ab 0t0 TCP *:postgresql (LISTEN) postgres 73 postgres 5u IPv4 0x8880707cadac18ab 0t0 TCP *:postgresql (LISTEN) Now shut it down (SIGTERM): $ sudo kill -15 73
