About Windows Support

Important!

  1. The Windows version of PostgreSQL includes PostGIS as an optional component.
  2. Because PostgreSQL is released on a different schedule from PostGIS, the PostGIS component in the official PostgreSQL Windows installer is often older than the PostGIS available here.
  3. If you want the latest PostgreSQL and the latest PostGIS at the same time, install PostgreSQL without PostGIS. Then get the PostGIS installer from here and install it seperately.

If you installed PostGIS 1.0.4 as part of the PostgreSQL windows installer you must remove it first. Start the PostgreSQL install program and select Modify to remove the PostGIS installation.

If you already were using PostGIS 1.0.4 you will need to perform a "soft upgrade" on the existing 1.0.x tables and functions. See the documentation for more information about the upgrade process.

For PostgreSQL 8.0 Users

The official PostgreSQL 8.0 installer included PostGIS 0.9.1 (a database dump and restore "hard upgrade" must be done in order to upgrade from 0.9.1). Please read the documentation for more information about the upgrade process.
