Installing pgvector
===================

``pgvector`` is supported on the same platforms as the Postgres
distribution you’re using. Support for ``pgvector`` starts with Postgres
13. For details, see:

- `EDB Postgres Advanced Server Product Compatibility <https://www.enterprisedb.com/platform-compatibility#epas>`_ 

- `PostgreSQL Product Compatibility <https://www.enterprisedb.com/resources/platform-compatibility#pg>`_ 

- `EDB Postgres Extended Server Product Compatibility <https://www.enterprisedb.com/resources/platform-compatibility#epas_extended>`_ 

Installation
------------

Before you begin the installation process:

- Install Postgres. See:

- :ref:`Installing EDB Postgres Advanced Server <Installing pgvector>` 

- `Installing PostgreSQL <https://www.postgresql.org/download/>`_ 

- :ref:`Installing EDB Postgres Extended Server <Installing pgvector>` 

- Set up the repository.

Setting up the repository is a one-time task. If you’ve already set up
your repository, you don’t need to perform this step.

To set up the repository, go to `EDB repositories <https://www.enterprisedb.com/repos-downloads>`_  and follow the
instructions provided there.

Install the package
-------------------

The syntax for the package install command is:

.. code:: shell


   #  For SLES, CentOS, RHEL and its derivatives

   sudo <package-manager> -y install edb-<postgres><postgres_version>-pgvector0

   #  For Debian and Ubuntu

   sudo <package-manager> -y install edb-<postgres><postgres_version>-pgvector-0

Where:

- ``<package-manager>`` is the package manager used with your operating
  system:
