| 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! ts |
