I think the answer is no, but I wanted to ask to be sure.
Given table below, is there any way to index field_a, field_b, array_a?
Create table table1 (
field_a integer not null primary key,
field_b integer not null,
...
array_a text[]
)
My app is running queries similar to this:
Select * from table1 where field_a = 123 and field_b = 456 and array_a @> ARRAY[’tag_xyz’];
The array_a can have unto 1000 elements. Currently these queries get very expensive if the array has any length to it.
Thanks for any ideas.
Thanks,
