ArcGIS 10.9.1 and ArcGIS Pro 2.9 requirements for PostgreSQL

ArcGIS supports connections to PostgreSQL databases and enterprise geodatabases in PostgreSQL.


For ArcGIS releases prior to 10.9 and ArcGIS Pro 2.8, see the system requirements on the ArcGIS Desktop website.

Visit Esri Technical Support for information on the Esri Supported Environment Policy.

Minimum supported database versions

The following versions of PostgreSQL and PostGIS are supported with ArcGIS. The specific versions listed are the minimum minor version supported and certified for each supported major release of PostgreSQL and PostGIS. Newer minor versions are supported, but are not certified unless otherwise stated. The PostgreSQL version and updates must also be supported by the PostgreSQL Global Development Group.

Pursuant to the PostgreSQL definition, the number in the x position indicates a minor version for PostgreSQL 10.x and later releases.

  • PostgreSQL 13.3 (64 bit)
    • PostGIS 3.1
  • PostgreSQL 12.7 (64 bit)
    • PostGIS 3.0.1
  • PostgreSQL 11.12 (64 bit)
    • PostGIS 3.0.1
  • PostgreSQL 10.17 (64 bit)
    • PostGIS 3.0.1


Due to changes in data type support beginning with PostgreSQL 12.x, if your database contains a geodatabase, you must use the pg_dump and pg_restore commands to upgrade to PostgreSQL 12.x or later. When you use this method to upgrade, it removes unused, unsupported OID fields from geodatabase system tables that would otherwise block you from upgrading PostgreSQL.

Once you upgrade to PostgreSQL 12.x or later, if the database contains a geodatabase, ArcGIS 10.8 and earlier clients and ArcGIS Pro 2.5 and earlier can no longer use the data; you must upgrade your ArcGIS clients.

Esri tests and certifies PostgreSQL installations that are available from For each PostgreSQL release that Esri supports, available PostGIS modules are also tested and certified. No other modules extending PostgreSQL functionality are included in Esri certification.

Supported operating systems

If you use a geodatabase in PostgreSQL or use the ST_Geometry type in a PostgreSQL database, the following operating systems have been tested and are the minimum supported version. Future updates or service packs on these operating system versions are supported and assumed to work unless otherwise stated. The operating system version and updates must also be supported by the operating system provider.


The following Linux operating systems have been tested:

Supported operating systemLatest update or service pack tested

Red Hat Enterprise Linux Server 8

Update 4

Red Hat Enterprise Linux Server 7

Update 9

SUSE Linux Enterprise Server 15

Service Pack 3

SUSE Linux Enterprise Server 12

Service Pack 5

Ubuntu Server 20.04 LTS


Ubuntu Server 18.04 LTS


Prior and future updates or service packs for these operating system versions are supported unless otherwise stated. The operating system version and updates must also be supported by the operating system provider.


Esri Technical Support is available for CentOS, Scientific Linux, and Oracle Linux versions that provide full binary compatibility with an equivalent supported Red Hat Enterprise Linux Server version. As a prerequisite for logging a software defect, Esri Technical Support will attempt to reproduce the issue on Red Hat Enterprise Linux Server. For Oracle Linux, support is predicated on the use of the Red Hat Enterprise Linux Server compatible kernel.

Cloud support

See Requirements for using ArcGIS with databases in the cloud for information on support for database services and databases deployed in the cloud.

Connections to PostgreSQL

ArcGIS applications that can connect to a PostgreSQL database contain the PostgreSQL client libraries that are required to make a connection. These applications include ArcGIS Server, ArcGIS Pro, ArcGIS Desktop, and ArcReader.

Only database authenticated connections are supported from ArcGIS to PostgreSQL.
