It seemed like that was the list's consensus, so I'll go off and do the
simple-constant case. We can always extend it later.
For reference, the plan is to add these options to CREATE/ALTER
FUNCTION:
COST float-constant (defaults to 1)
ROWS float-constant (defaults to 1000)
feeding into two float4 columns added to pg_proc. ROWS is only
allowed/meaningful for set-returning functions. COST is implicitly
scaled by cpu_operator_cost.
