I had to apply the first patch by hand (on 9f13376396), so this looks due for a rebase. Patches 2-4
applied fine.
Compiles & passes tests after each patch.
The overall idea seems like a good improvement to me.
A few remarks about cleaning up the RangeTblEntry comments:
After the fourth patch we have a "Fields valid in all RTEs" comment twice in the struct, once at the
top and once at the bottom. It's fine IMO but maybe the second could be "More fields valid in all RTEs"?
The new order of fields in RangleTblEntry matches the intro comment, which seems like another small
benefit.
It seems like we are moving away from ever putting RTEKind-specific fields into a union as suggested
by the FIXME comment here. It was written in 2002. Is it time to remove it?
This now needs to say "above" not "below":
/*
* join_using_alias is an alias clause attached directly to JOIN/USING. It
* is different from the alias field (below) in that it does not hide the
* range variables of the tables being joined.
*/
Alias *join_using_alias pg_node_attr(query_jumble_ignore);
Re bloating the serialization output, we could leave this last patch until after the work on that
other thread is done to skip default-valued items.
