Comment (by strk):

 I've implemented the suggestion from Chapman Flack (found in the pgsql-
 hackers thread above) into
 https://git.osgeo.org/gitea/postgis/postgis/pulls/45

 Basically, we install an empty postgis--unpackaged.sql script and use it
 to fool PostgreSQL into thinking we need unpackaged--targetversion for
 upgrading it...

 The run_test.pl was changed to stop using the `FROM unpackaged` syntax and
 instead use the workaround syntax of creating the empty extension and then
 upgrading it.
