pushJsonbValue was accepting jbvBinary objects passed as WJB_ELEM or WJB_VALUE data. While this succeeded, when those objects were later encountered in attempting to convert the result to Jsonb, errors occurred. With this change we ghuarantee that a JSonbValue constructed from calls to pushJsonbValue does not contain any jbvBinary objects. This cures a problem observed with jsonb_delete. This means callers of pushJsonbValue no longer need to perform this unpacking themselves. A subsequent patch will perform some cleanup in that area. The error was not triggered by any 9.4 code, but this is a publicly visible routine, and so the error could be exercised by third party code, therefore backpatch to 9.4. Bug report from Peter Geoghegan, fix by me.
