Machine is a Macbook Pro 2014 / OS X Yosemite 10.10 with Postgres 9.3.5 installed via Homebrew.
I can only connect to my local postgres instance if I do NOT specify a host. This works:
psql -Umyuser -d mydb sql (9.4.4) Type "help" for help. myuser=#
-h localhost does not:
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.
It pauses for a long time before I get this message.
I am trying to set up a third party tool that seems to want to specify localhost, so it is not an option just to leave that off.
If I understand what I've read correctly elsewhere, postgres behaves differently if you're using TCP/IP, and specifying
-h localhost forces that. Accordingly I have added the following in
local all all trust # 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
(127.0.0.1 AND localhost seems redundant but desperation drives superstition) … and in
listen_addresses = 'localhost' port = 5432
netstat confirms that Postgres is listening to that port:
☁ ~ netstat -an | grep 5432 tcp4 0 0 127.0.0.1.5432 *.* LISTEN tcp6 0 0 ::1.5432 *.* LISTEN d8d7c0e31d5add1d stream 0 0 d8d7c0e326b18a1d 0 0 0 /tmp/.s.PGSQL.5432
All permissions are set on the socket file:
~ ls -l /tmp/.s.PGSQL.5432 srwxrwxrwx 1 fritz wheel 0 12 Jul 13:27 /tmp/.s.PGSQL.5432
/etc/hosts has an entry for localhost:
127.0.0.1 localhost ::1 localhost
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
There's nothing named
psql elsewhere on my system that seems like it could be hijacking this process:
~ sudo find / -name psql /Applications/pgAdmin3.app/Contents/SharedSupport/psql /Users/fritz/devtools/phantomjs/src/qt/config.tests/unix/psql /Users/fritz/Qt/5.3/Src/qtbase/config.tests/unix/psql /Users/fritz/Qt/5.3/Src/qtbase/src/plugins/sqldrivers/psql /Users/fritz/Qt/5.3/Src/qtbase/src/sql/drivers/psql /usr/local/bin/psql /usr/local/Cellar/postgresql/9.4.4/bin/psql
UPDATE: telnet connects to localhost 5432 for a while and then is disconnected:
~ telnet localhost 5432 Trying ::1... Connected to localhost. Escape character is '^]'. Connection closed by foreign host.
UPDATE 2: I used wireshark to spy on tcp localhost port 5432. Trouble is, I don't know what I should see and whether/how the results are wrong. Hoping someone out there can make something of this capture file.
