For my 2c, at least, I still don't really get why that split was done. > To upgrade, there is now postgis_extensions_upgrade() function, that > unpackages the raster part out of postgis extensions, upgrades it, and > packages raster functions back into postgis_raster by utilizing FROM > UNPACKAGED. > Removal of FROM UNPACKAGED breaks PostGIS 2.5 -> 3.0 upgrade path, and > we haven't yet found a proper replacement since such removal wasn't > something we were expecting. I agree that there probably isn't a very good path to allow an extension to be split up like that without having to drop some things. An alternative would have been to *not* split up postgis, but rather to have a postgis_raster and a postgis_vector. Adding in support for other ways to migrate a function from one extension to another would make sense too. Thanks, Stephen
