with the following table:
Table "public.foo"
Column | Type | Modifiers
--------+------+-----------
t | text |
Indexes:
"a" btree (t)Shouldn't queries that use ... where t like '%something%'
benefit from "a" when t is NULL in almost all cases, since the query planner could use "a" to access the few non-NULL rows quickly? It doesn't seem to work right now.
(I assume that it would make no difference if the index "a" was partial, excluding NULLs)
