Good catch!

In addtion to your patch, we should add the description for
the multicolumn brin index, like the following one in the doc?

---------------
A multicolumn GIN index can be used with query conditions that
involve any subset of the index's columns. Unlike B-tree or GiST,
index search effectiveness is the same regardless of which index
column(s) the query conditions use.
