In plpgsql, don't preassign portal names to bound cursor variables.
A refcursor variable that is bound to a specific query (by declaring
it with "CURSOR FOR") now chooses a portal name in the same way as an
unbound, plain refcursor variable. Its string value starts out as
NULL, and unless that's
Accept "+infinity" in date and timestamp[tz] input.
The float and numeric types accept this variant spelling of
"infinity", so it seems like the datetime types should too.
