Hm, seems, it's useful feature, but I suggest to make separate function jsonb_any_to_tsvector and add support for boolean too (if you know better name for function, do not hide it). Changing behavior of existing function is not obvious for users and, seems, should not backpatched.the consistency of FTS.I think this is a bug, which needs to be fixed, else inconsistency with existing full text search will be gets deeper.
