To upgrade from PostGIS version 2.5.4 (or lower) to 3.1.2, you must perform the following actions:
- Since the return type of the raster functions have changed, you must drop and re-create the raster extension as part of the upgrade process.
- Before upgrading to version 3.1.2, you must upgrade to 3.1.1 first as an intermediate step.
- When the PostGIS data has a dependency on the raster functions, upgrading to PostGIS 3.1.2 requires dumping and reloading the data.
See the upgrade section for details.
