I've looked at the last question and the link that it referenced, but I did not find a file called 'uninstall-postgresql' when I run this command. PostgreSQL is not typically problematic but it's worth mentioning that Postgres.app can’t start when another server is already running on the same port (default: 5432). We recommend to uninstall other PostgreSQL installations before using Postgres.app.
To uninstall PostgreSQL on a Mac system, assume the identity of an operating system superuser, and navigate into the folder in which the uninstaller resides: /Library/PostgreSQL/10 Then, invoke the uninstaller with the command. This is the native Mac app that you see when you double click Postgres.app in the Finder. For compatibility reasons we build the different parts on different versions of macOS. The binaries for PostgreSQL 9.4 - 10 are built on macOS 10.10 with Xcode 7.2.1.
If you’re planning to run PostgreSQL on a Mac, it’s important to know how to install it properly. There are three common ways to install Postgres on a Mac: using Homebrew’s
brew install
command, downloading the DMG interactive installer for Postgres.app or using MacPorts. In this article, we’ll provide step-by-step instruction for all three of these methods, so you can choose the installation process that works best for you.Prerequisites

Install PostgreSQL on a Mac
As we mentioned earlier, there are three common ways to install PostgreSQL on macOS. You can use a downloadable DMG installer from Postgres.app, a Homebrew repository for Postgres or a MacPorts installation that uses the
port
command line interface.It’s also possible to build a binary of PostgreSQL from source using a tarball archive or to run Postgres in a Docker container; however, we won’t be providing instructions for these alternatives in this article.
Install Postgres using the Postgres.app
The easiest way to install Postgres on a Mac is to visit the Postgres.app downloads page and get the latest stable version of PostgreSQL as a DMG interactive installer.
Once the download is complete, navigate to your Downloads directory in a Finder window and then double-click on the DMG file to mount the installer. After mounting it, you should see a window pop up that will allow you to drag and drop the Postgres.app to your Applications folder.
Once you complete the installation steps, you should be able to run PostgreSQL by double-clicking the app’s icon in the Applications folder. You can also choose to have Postgres.app run by default– just add the application to your Login Items list in System Preferences.
Use the following
export
command in a macOS Terminal window to add the Postgres.app path to your current PATH
environment variable:export PATH='/Applications/Postgres.app/Contents/Versions/11/bin:$PATH' |
Install PostgreSQL using Homebrew
If you’d prefer to use Homebrew to install Postgres, you can do so using the
brew install
command. You’ll need to install the latest version of Homebrew using Ruby if you haven’t already. To do this, use the following command:/usr/bin/ruby -e'$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)' |
If you’re running the latest Catalina version of macOS, the output of this command should look like the following:
> This script will install: /usr/local/bin/brew /usr/local/share/doc/homebrew /usr/local/share/man/man1/brew.1 /usr/local/share/zsh/site-functions/_brew /usr/local/etc/bash_completion.d/brew /usr/local/Homebrew |
It may take a few minutes to install Homebrew depending on your internet connection. When the installation is complete, the next step is to “doctor” the Homebrew installation and update its repositories with this compound command:
NOTE: The latest versions of Homebrew will update the repository before installing packages.

Mac install of Postgres using ‘brew’
Now that we’ve installed the latest version of Homebrew, we can use the
brew install
command to install PostgreSQL:brew install postgresql |
NOTE: In Homebrew, the
postgres
“keg” is simply an alias for postgresql
, so brew install postgres
will work the same way.Once the installation is finished, you can use the
postgres -V
or psql -V
commands to return the version number and verify that the installation was successful. You can also use the brew list
command to view a list of all locally installed packages using Homebrew.psql command not found
If you get an error stating
psql: command not found
, you may have to export the path for the Homebrew installation using the following command:As an alternative, you can also add the following
PATH
line to your ~/.bash_profile
, ~/.bashrc
or ~/.zprofile
file:PATH='/Library/PostgreSQL/11/bin:$PATH' |
After editing any of these files, be sure to save the changes. You can have the new settings take effect by running the
source
command followed by the file name:Try executing the
psql
command again after making these changes to verify that the PATH
for PostgreSQL and psql has been set.Start the Postgres server
With Homebrew, you can use the
brew services start
command to have Postgres start in the background:brew services start postgresql |
If you’d prefer to run Postgres as a temporary background service, use the following
pg_ctl
command instead:You can use Homebrew’s
enable
command to have PostgreSQL start automatically whenever you restart your Mac:brew services enable postgresql |

command:Install Postgres using MacPorts
The last method we’ll discuss in this article involves using the MacPorts package manager for macOS. To install Postgres on a Mac this way, visit the release page for MacPorts and download a
.pkg
installer that matches your version of macOS. Once the download is complete, you can navigate to your Downloads directory in a Finder window and double-click the package installer. Follow the steps for the interactive installer, and open a terminal window when you’re done.NOTE: MacPorts also requires the Xcode library.
In order to install a package, you’ll need to export a path for Macport’s
port
command. Execute the following export
command in a terminal window:exportPATH=/opt/local/bin:/opt/local/sbin:$PATH /opt/local/bin |
You can also open your
.bash_profile
or .zprofile
file and append the following:After saving your changes to the file, go back to your terminal and input
source ~/.bash_profile
or source ~/.zprofile
to load the changes.Use Macport’s ‘port’ command to install Postgres
At this point, we’re ready to use the

There are two main ways to install PostgreSQL on mac OS X.
- Downloading the app file from postgresapp.com.
Using Homebrew
Homebrew can be installed by running the following command in a terminal:
/usr/bin/ruby -e '$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)'
If Homebrew is already installed, make sure that it is up to date by running:
brew update
Then ensure there are no conflicts or errors using:
brew doctor
Homebrew is a powerful package manager with many uses, including installing and running postgreSQL. This can be done by typing the following command into a terminal:
Asus splendid monitor driver for mac. Now that postgres is installed the default server can be started by running the command:
This will start up a postgres server hosted locally on port 5432. Voice control app download for android phone. The server will be run out of the directory
/usr/local/var/postgres
.Install Postgres On Mac
It can now be accessed by typing the following command:
This will connect to the server and access the postgres database. Once this is done:
- Schemas and tables can be created
- Data can be loaded and deleted from the database
- Queries can be run
The process should look like this:
This shows that the server has been started and can be connected to.

(Optional) Creating a Custom Data Directory
A custom data directory can also be used for a server. To do this, first create a directory to be used as the server location. https://heavydiary708.weebly.com/filter-effect-djay-pro.html. For example, create a directory called myData in the home directory:
Once the directory is created, the server can be initialized. This means that we configure the directory and add the necessary files to run the server. To do this run the
initdb
command as shown:This will fill the myData directory with files necessary to run the server:
Now that the server is initialized and the log file is created, you can start the server from this directory. To do this use the command and substitute in for the specified values:
The “Data Directory” refers to the directory that was just initialized (in this case myData). The “Log file” is a file that will record server events for later analysis. Generally log files are formatted to contain the date in the file name (e.g. “2018-05-27.log” or “myData-logfile-2018-05-27.log”) and should be stored outside of the database that they are logging so as to avoid unnecessary risks. Log files can be dense to read but are very useful for security and debugging purposes:
The command above will generate a log file like the one shown, start the server, and tie the log file to the server. If a log file is not specified, events will be logged to the terminal:
The server will only start if the port is free. If the default server is running it must first be stopped using the
pg_ctl -D /usr/local/var/postgres stop
command:Once started, it can be connected to the same way as before using:
Install Postgres Linux
Using PostgreSQL App
To run a server through the postgres app, the first step is to download the program. The app can be downloaded on postgresapp.com. Once the app is downloaded and moved into the applications folder, the app can be opened.
Open the Postgres app:
In order to start the server, click the start button.
This will start the server. Details on the server can be found by opening the server settings:
This interface shows all the essential information regarding the server. It also allows the port to be changed very easily. This is useful because multiple PostgreSQL servers can
Note: To change the port in the terminal, the ‘postgres.conf’ file (which can be found in the data directory) must be edited. This looks like the following:
Using Terminal with the PostgreSQL App
Once the app has been downloaded, command line tools can be used as well. These tools can be accessed by typing:
Uninstall Postgres On Linux
For example, the ‘postgres’ database on the server can be connected to using the psql tool with postgres as an argument:
Rather than typing out the full path each time however, the path can be added to a file that will allow significantly easier access to the tools, allowing the tools be accessed from any directory on the computer. To do this, the following command can be run in the terminal:
Once this is done, the ‘postgres’ database can be accessed by simply typing:
