For those that are not developers:

The proposed changes referenced in the above URLs take old portions PostgreSQL
C code which were previously on a larger C file and move them to a new module
which has the PostgreSQL header. Modules need to have a MODULE_LICENSE() tag,
and if one is not used the kernel assumes the module is proprietary. The above
code lacks a MODULE_LICENSE() tag as such currently the driver is proprietary.
Clearly that needs to be fixed before upstreaming.
