Arrange for function default arguments to be processed properly in expressions
Tom Lane <tgl@sss.pgh.pa.us>
Arrange for function default arguments to be processed properly in expressions that are set up for execution with ExecPrepareExpr rather than going through the full planner process. By introducing an explicit notion of "expression planning", this patch also lays a bit of groundwork for maybe someday allowing sub-selects in standalone expressions.
