I don't know if I get your point here. On the v4 patch we have:
-       "test_custom_ext_paths|1.0|1.0|Test extension_control_path",
+       "test_custom_ext_paths|1.0|1.0|Test extension_control_path|$ext_dir_canonicalized/extension",

The $ext_dir_canonicalized in this case is a custom path configured on
extension_control_path GUC that the "test_custom_ext_paths" extension
was installed.

Fixed on attached v5

On this new v5 version I also swap the order of "comment" and "location"
columns as it was suggested by Michael.
