Suggest editsSupported platforms
For information about the platforms and versions supported by PostgreSQL, see EDB's Platform Compatibility page.
Downloading installers
To download PostgreSQL installers for Windows and Mac, see the EDB downloads page.
Prebuilt packages and instructions for the most common Linux and Unix systems are available from postgresql.org.
Hardware requirements
The following installation requirements assume you selected the default options during the installation process. The minimum hardware required to install and run PostgreSQL is:
- 1 GHz processor
- 2 GB of RAM
- 512 MB of HDD
Additional disk space is required for data or supporting components.
Software prerequisites
User privileges
On a Mac system, you need superuser privileges to perform a PostgreSQL installation. To perform an installation on a Windows system, you need administrator privileges.
If you're installing PostgreSQL on a Windows system that's configured with User Account Control (UAC) enabled, you must assume administrative privileges to invoke the graphical installer.
Windows-specific software requirements
Apply any Windows operating system updates before invoking the PostgreSQL installer. If the installer encounters errors, exit the installer. Make sure that your Windows version is up to date, and then restart the installer.
Mac OS X-specific software requirements
PostgreSQL installation on Mac OS X differs slightly from other platforms. The distribution is in a different format, and additional configuration might be required.
The Mac OS X installer is an app bundle, which is a set of files and directories in a prescribed format. The installer is available as a disk image (.dmg) file from the website or as an archive (.zip) from Stack Builder. To extract the installer, you can either:
- Mount the disk image and copy the installer to the desired location.
- Run it directly from the disk image.
