Hi, >From the terminal in Mac OS X Yosemite, connecting to homebrew installed 9.4.4, I have a problem if I specify the host (I know this comes up all the time, bear with me as I have done a fair amount of digging already). This works: psql -Umyuser -d mydb sql (9.3.5) Type "help" for help. myuser=# Server log shows: [unknown] LOG: connection received: host=[local] myuser [local]LOG: connection authorized: user=myuser database=myuser So that's all good. If I use -h it doesn't work: psql -Umyuser -d mydb -h localhost psql: server closed the connection unexpectedly This probably means the server terminated abnormally before or while processing the request. Server log: [unknown] LOG: connection received: host=::1 port=51186 (... and that's it, no connection authorized line) I've checked the normal things people suggest, e.g. postgresql.conf: listen_addresses = 'localhost' # also '*', '127.0.0.1', '::1' port = 5432 and pg_hba.conf: # IPv4 local connections: host all all 127.0.0.1/32 trust host all all localhost trust # IPv6 local connections: host all all ::1/128 trust And psql and pg_ctl are pointing to the same installations: ~ which psql /usr/local/bin/psql ~ ll /usr/local/bin/psql /usr/local/bin/psql -> ../Cellar/postgresql/9.4.4/bin/psql ~ which pg_ctl /usr/local/bin/pg_ctl ~ ll /usr/local/bin/pg_ctl /usr/local/bin/pg_ctl -> ../Cellar/postgresql/9.4.4/bin/pg_ctl People have suggested checking for stuff on my machine that could close connections. The Mac OS firewall is off and so is pf (Mac OS packet filter). This is all after upgrading (I had the same problem with 9.3.5) and reinstalling. Anyone got more clues for me?
