Ascending / Descending Indexes

[Michael Gould <mgould@xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx>]

In some SQL engines the engine doesn't need to define both Ascending and Descending indexes on the same column.  Does Postgres need to have indexes defined for both Ascending and Descending sorts?  We use quite a few of these types of sorts.

 

Best Regards
