History
Tom Lane addc42c339 Create the planner mechanism for optimizing simple MIN and MAX queries 
into indexscans on matching indexes.  For the moment, it only handles
int4 and text datatypes; next step is to add a column to pg_aggregate
so that all MIN/MAX aggregates can be handled.  Per my recent proposal.
