Fixed, gin_numeric_cmp is marked as strict.

SQL NULL: GIN doesn't support it (amindexnulls/amsearchnulls == false)
C NULL: NULL-numeric could be returned only by gin_extract_query_numeric which
cannot be called by user directly because of internal type of argument.
GIN doesn't do anything with values returned by gin_extract_query_numeric except
providing they as an argument for comparing functions.
