http://www.postgresql.org/docs/9.1/static/gin-implementation.html """As of PostgreSQL 9.1, NULL key values can be included in the index. Also, placeholder NULLs are included in the index for indexed items that are NULL or contain no keys according to extractValue. This allows searches that should find empty items to do so."""
