7/24/2023 0 Comments Postgres osxSince I do not want to repeat this experience in future updates, I think it is a good idea to create my database on a separate cluster/instance. OSX 10.8 "/Library/Server/PostgreSQL/Data"Īfter the update the /var/pgsql folder is gone. OSX 10.8: /Applications/Server.app/Contents/ServerRoot/usr/bin/postgre Apby Aveek Das In this article, I am going to discuss different ways in which you can install and setup Postgres Database on a Mac. To better understand what has happened: > Which postgres Unfortunately, the setup process for PostgreSQL 9.1.4 has created these brand new databases: collab, webauth, postgres, tempalte0, template1 all the other databases and roles created by me seem to have been deleted! The reason is because neither postgres role nor (aka whoami on your command line) are in postgres.After upgrading my MacMini home server from OS-X 10.7 (Lion) Server to OS-X 10.8 (ML) Server.app, I saw PostgreSQL 9.1.4 was released. sudo -u postgres pgctl start could not identify current directory: Permission denied pgctl: no database directory specified and environment variable PGDATA unset PGDATA isnt set. # psql: error: connection to server on socket "/tmp/.s.PGSQL.5432" failed: FATAL: role "postgres" does not exist mac os x - Start, stop, configure PostgreSQL through Mac terminal - Database Administrators Stack Exchange Start, stop, configure PostgreSQL through Mac terminal Ask Question Asked 7 years, 2 months ago Modified 4 years ago Viewed 16k times 2 I am having basic problems using PostgreSQL on my Mac OSX Yosemite, through the terminal. Attempt 1 Trying something else, omitting the -D as I might be overcomplicating things. # sudo: error initializing audit plugin sudoers_audit # createuser: error: connection to server on socket "/tmp/.s.PGSQL.5432" failed: FATAL: role "" does not exist ![]() Psycopg is the most popular PostgreSQL database adapter for the Python. What I have triedĪmong other similar commands, for me all these commands failed: createuser -s psycopg2 - Python-PostgreSQL Database Adapter. I am adding an answer for a case I have not seen here, which is an edge case if you have multiple users on the same machine and the user who is trying to use postgres services is not the user who installed postgres on the machine. If user is really the DB superuser you can create another DB superuser and a private, empty database for him: CREATE USER postgres SUPERUSER ĬREATE DATABASE postgres WITH OWNER postgres īut since your postgres.app setup does not seem to do this, you also should not. So you could try this command to login: sudo -u user psql user ![]() So I think your setup simple uses user as the superuser. And looking at the output of your \l command: The permissions for user on the template0 and template1 databases are the same as on my Ubuntu system for the superuser postgres. ![]() ![]() Choose the directory where you wish to install the folder and. If there is one, you can use that to login. To install the Postgre on Mac OS X: Download svg viewer Select the location and components. If there is not at least one role with superuser, then you have a problem :-) Postgres | Superuser, Create role, Create DB | Later in the login process it might also stumble over the missing database.īut the first step is to check the missing role: What is the output within psql of the command \du ? On my Ubuntu system the relevant line looks like this: List of roles Note that the error message does NOT talk about a missing database, it talks about a missing role. NOTE: If you installed postgres using homebrew, see the comment from below.
