Hello,

I have a column with a small number of distinct values, indexing this
one with a standard BTree is useless. How do I  can index this column
efficiently? I searched and it seems that pg doesn't support the
creation of persistent bitmap indexes... Is that feature planned in next
releases of pg?

Thanks
Bruno Lavoie
