+jsonb_opx
+=========
+
+Missing operators for jsonb in PostgreSQL 9.4, this may contain some errors and bad form as it's primarily just experimentation (i'm not a frequent C programmer; but everyone has to start somewhere right?).  Please test that it suits your requirements before using in any production scenario.
+
+Provides
+--------
+
+The following behave like hstore 1.x operators, i.e. without nested jsonb traversal
+
+* deletion using **-** operator
+  * jsonb_delete(jsonb, text)
+  * jsonb_delete(jsonb, text[])
+  * jsonb_delete(jsonb, jsonb)
+* concatenation using **||** operator
+  * jsonb_concat(jsonb, jsonb)
+* replacement using **=#** operator
+  * jsonb_replace(jsonb, jsonb)
+
+The following are intended to eventually function like hstore 2.0 operators
+
+* deletion at chained path using **#-** operator
+    jsonb_delete_path(jsonb, text[])
+* replacement at chained path using function
+    jsonb_replace_path(jsonb, text[], jsonb)
