Hi friends!
We tried to index an array function like this:
CREATE INDEX my_arr_index ON my_table USING GIN ( my_arr_func( my_col ) )
But the planner can’t seem to figure out how to use the index with any query! It doesn’t work with any array operators.
SELECT * FROM my_table WHERE ARRAY[ 123 ]::INT[] && my_arr_func( my_col )
Even weirder, an empty array correctly uses the index:
SELECT * FROM my_table WHERE ARRAY[]::INT[] && my_arr_func( my_col )
Is there any way to coerce Postgres into using this index? Thanks!
