+Subject: [PATCH] Don't remap all versions of Npgsql to 4.0.0.0
+
+Mono has a list of assemblies considered "internal", whose versions are automatically remapped to the distro default version.
+
+Since we no longer bundle Npgsql, it is up to individual distributions to package their own Npgsql - but Mono cannot load any version other than 4.0.0.0 from the GAC, due to this remapping:
+
+Mono: Assembly Ref addref npghello[0x17e2fd0] -> mscorlib[0x1789c00]: 2
+Mono: The request to load the assembly Npgsql v2.2.7.0 was remapped to v4.0.0.0
+Mono: Assembly Loader probing location: '/usr/lib/mono/gac/Npgsql/4.0.0.0__5d8b90d52f46fda7/Npgsql.dll'.
+
+Npgsql, Version=2.2.7.0, Culture=neutral, PublicKeyToken=5d8b90d52f46fda7
