Versions of PostgreSQL supported by which versions of PostGIS
| PostgreSQL Version | PostGIS 1.3 | PostGIS 1.4 | PostGIS 1.5 | PostGIS 2.0 Trunk |
| 7.2-7.4 | Yes (not windows) | No | No | No |
| 8.0 | Yes (not windows) | No | No | No |
| 8.1 | Yes | No | No | No |
| 8.2 | Yes | Yes | No | No |
| 8.3 | Yes | Yes | Yes | No |
| 8.4 | Yes | Yes | Yes | Yes |
| 9.0 | No | No | Yes | Yes |
| 9.1 | No | No | Yes? | Yes |
For the question mark items Yes? support may be dropped for those before the next micro or the official release. PostGIS 1.5 based on what we know currently happens to work on 9.1, but this may change in a micro release, so should be treated as not supported. Note we plan to drop support for PostgreSQL 8.3 in PostGIS 2.0. PostgreSQL 9.1 is now in development and in beta1 phase.
As a general rule, the PostGIS Project Steering committee tries to maintain support of PostGIS for at least two versions of PostgreSQL. We sometimes support more than 2 PostgreSQL versions, if requirements do not necessitate bumping up requirement without too much effort. We will rarely, if ever, support more than 3 PostgreSQL versions on any release.
We don't currently support 64-bit PostgreSQL Windows (which was introduced in PostgreSQL 9.0+).
Versions of GEOS support for PostGIS
The below chart shows which versions of GEOS work with which versions of PostGIS. The none means that you can get that version to work without GEOS, though its not recommended since a lot of functions will not be installed.
For the not recommended, this means that while you can get PostGIS to work with those versions, you'll be missing out on some PostGIS functions such as ST_Covers, ST_CoversBy and for PostGIS 1.5 the ST_HausdorffDistance and enhancements to ST_Buffer (both speed and functionality). GEOS 3.1 brought cascade union. GEOS 3.2 brought faster buffering and buffering enhancements, plus numerous enhancements with dealing with tolerance issues when unioning. GEOS 3.3 brought ST_ValidReason, ST_MakeValid etc (in the PostGIS 2.0 releases), so these functions will be disabled in PostGIS 2.0 if you are not running GEOS 3.3.
| Geos Version | PostGIS 1.3 | PostGIS 1.4 | PostGIS 1.5 | PostGIS 2.0 |
| None | Yes (not recommended) | No | No | No |
| 2.2 | Yes (not recommended) | No | No | No |
| 3.0 | Yes | Yes (not recommended) | No | No |
| 3.1 | Yes | Yes | Yes (not recommended) (requires 3.1.1+) | No |
| 3.2 | Yes | Yes | Yes | Yes (not recommended) |
| 3.3 | Yes | Yes | Yes | Yes |
