PostgreSQL 9.4 Released
Whats a good place to suggest a postgresql [json] improvement, my message was intercepted when posting to pg-performance. A major one at the moment is that offset does the select projection on discarded rows (common to use offset in paging), under normal circumstances this isn't a problem, however when does a json operation such as reading a field ->> this causes major performance degrading. Note of course only immutable functions can this optimization apply. There are several workarounds but if PostgreSQL wants to win back some nosql heads it should be straight forward.In addition to update a json field isn't straight forward, these operations should be supported by first class inbuilt functions.Its getting close but its not quite a nosql killer yet if they are targetting people who didn't originally come from rdbms background..
