If the CREATE EXTENSION X FROM UNPACKAGED is supposed to only work
when the unpackaged is the same version as the target extension
version we should make sure to add a check in that upgrade script
to avoid violation of that meaning. Could you please ticket this
as a bug ?

The bug would be: `CREATE EXTENSION xx FROM UNPACKAGED` results in
corrupted database (leaving old signatures behind). Right ?
