Question: jsquery in order by
I see how I can use the jsquery @@
operator in a WHERE
clause or in a CHECK
constraint. Is there an operator in either of the opclasses which would allow the use of the index in an ORDER BY
clause? For example, suppose I have a table full of jsonb documents which look like:
{"time":1430432587, "place":"zoo", "animal_counts":{"monkeys":77, "tigers":3, "elephants":9.4}}
I would like to sort by animal_counts.tigers
and I would like that sort to use the index.
Unfortunately, that's not possible to this in GIN indexes yet. You could create btree expression index on js->'animal_counts'->'tigers'.
What is the status of VODKA indices making it into Postgres master?
