Hi all, (please, look at and analyze the situation)
does BTree index support intersection?
please, I'm not talking about combination of queries, and yes of indexes!
for example: I have 2 indexes, the first in on (date_inclusion ,
date_cancellation ) and the other is in (date_cancellation ,
date_inclusion ).
so, when I do a query like this:
select * from mytable
where (date_inclusion <= '01/01/2003') and (date_cancellation >
'01/01/2003')
I think that PostgreSQL should use those 2 indexes and do an intersection
automatically between they
