Hello,

I wonder if the process of index creation can benefit from other indexes.

EG: Creating a partial index with predicat based on a boolean column, will
use an hypothetic index on that boolean column or always use a seq scan on
all rows ?

Goal is to create partial indexes faster.

Explain command does not work with Create index.

Thanks by advance

Nicolas PARIS
