Reservation for aligment. It's allowed to be v->size greater than it's actually
needed. Fixed.

added a check_stack_depth()

Jentry + header + reservation for aligment

ereport(ERRCODE_NUMERIC_VALUE_OUT_OF_RANGE)
2 * sizeof(uint32) - minimal size of object element (key plus its value)

fixed

No idea, i don't have an objection

send/recv for hstore is fixed too. Should I make new version of patch? Right now
it's placed on github. May be Andrew wants to change something?
