написано следующее:
"Another example is that if we have separate indexes on x and y, one
possible implementation of a query like WHERE x = 5 AND y = 6 is to use each
index with the appropriate query clause and then AND together the index
results to identify the result rows".
You mean "WHERE x = 5 OR y = 6"?
result from index scan by x + result from index scan by y
Thx.
