After that I downloaded pgadmin3 and I am indeed able to connect to the database.when I run 'psql' I get the following error:psql: could not connect to server: No such file or directory Is the server running locally and acceptingAfter hours of googling I read about some $PATH issues, so I put this into my .bashrc:export PATH=/Library/PostgreSQL/9.1/bin:$PATHHowever, this doesn't solve the error above at all. After some more hours of googling I tried to run 'psql -l localhost -U postgres'. This gives another error:psql: could not connect to server: Connection refused Is the server running on host "localhost" (::1) and accepting TCP/IP connections on port 5432?could not connect to server: Connection refused Is the server running on host "localhost" (127.0.0.1) and accepting TCP/IP connections on port 5432?could not connect to server: Connection refused Is the server running on host "localhost" (fe80::1) and accepting TCP/IP connections on port 5432?After some more googling I tried to edit /Library/PostgreSQL/9.1/data/pg_hba.conf and replaced all occurrences of 'md5' with 'trust'.Then I changed user to postgres and executed 'pg_ctl stop' and 'pg_ctl start', switched back to my own user and tried to connect again, no luck.Here are some more infos:[~]$ which psql/Library/PostgreSQL/9.1/bin/psqlps aux | grep postgrespostgres 19022 0.0 0.0 2446096 484 ??

In your case it's 19015 (shown with my PID):> sudo lsof -p 286 | awk '$5 == "unix" && $NF ~ /\// { print $NF }'/tmp/.s.PGSQL.5432You can leave off the awk, but basically it's getting the UNIX socket on which postgres is listening. From there, you can use the -h option to psql (but only include the directory).> psql -h /tmp template1template1=# \qIf that doesn't work, you can check the lsof output to show you what TCP port it's actually listening on, and if it's not 5432, use the -p option to postgres 这篇关于如何在OSX Lion上安装PostgreSQL 9.1的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！ 上岸，阿里云！
