create index index_002 on my_table using btree (a003) where a001=true and a002=false;
Now take this query:
select * from my_table where a001=true;
Which index will postgres pick? I'm wondering how postgres goes about picking an index to consider.
Neither…since neither partial index condition is present in the where clause of the query.
