What I'm maintaining is that such authors should be warned about the risk, and discouraged from installing any wildcard-containing script UNLESS they deal with downgrade protection. PostGIS does deal with that kind of protection (yes, could be helped somehow in doing that by PostgreSQL). > I'm not unsympathetic to the idea of trying to support multiple upgrade > paths in one script.

Would you be ok with a stricter pattern matching ? Something like: postgis--3.3.%--3.3.ANY.sql postgis--3.3.ANY--3.4.0.sql Would that be easier to promise something about ? --strk;
