For more information on Homebrew Services, read this excellent blog post that explains how it works. If you don't have Homebrew Services installed, just $ brew tap homebrew/services This will connect to the server and access the postgres database. In the following example, we connected to a database named mydb. Once connected, we can run SQL queries on the database. You have to provide the database name after c. To verify that the local postgres daemon isn't running, check your installed homebrew services: $ brew services list It can now be accessed by typing the following command: psql postgres. This psql command is used to connect to a specific database.
PSQL MAC FULL VERSION
Type the following SQL statement within the prompt to check the current version: SELECT version () The resulting output provides the full version and system information for the PostgreSQL server. Now you can use psql to connect to remote Postgres servers, and won't be running a local one, although you could if you really wanted to. Access the PostgreSQL shell prompt by typing the following command: sudo -u postgres psql. Or, if you don't want/need a background service you can just run: To have launchd start postgresql now and restart at login:
=> /usr/local/Cellar/postgresql/9.6.5/bin/initdb /usr/local/var/postgres So the "correct way" to get the psql application is indeed to install the postgres formula, and you'll see toward the bottom of the "caveats" section that it doesn't actually run the database, it just puts the files on your system: $ brew install postgres You can easily interact with PostgreSQL database with Python.
PSQL MAC MAC OS
Homebrew only really has the postgres formula, and doesn't have any specific formula that only installs the psql tool. You can install PostgreSQL on Windows, Mac OS and Linux very easily.
