BITMAP INDEXES...

Hi,

I have learnt from certain texts  that bitmap indexes are very useful for
large DSS (decesion support systems).

bitmap indexes are currently not available in postgresql.

My question is in what way is a normal btree index in pgsql
inferior to bitmap indexes (found in oracle for example).

is it just in terms of space requirements for performance too?
