Extend GUC concepts of parse_hook and assign_hook to all four supported
datatypes, not only strings. parse_hook is useless for bool, I suppose,but it seems possibly useful for int and double to apply variable-specificconstraints that are more complex than simple range limits. assign_hookis definitely useful for all datatypes --- we need it right now for boolto support date cache reset when changing Australian timezone rule setting.Also, clean up some residual problems with the reset all/show all patch,including memory leaks and mistaken reset of PostPortNumber. It seemsbest that RESET ALL not touch variables that don't have SUSET orUSERSET context.
