this code was last gone over, there wasn't really any alternative to
globals because we didn't have the PlannerInfo struct being passed all
through the planner code. Now that we do, we can restructure things
to avoid non-reentrancy. I'm fooling with this because otherwise I'd
have had to add another global variable for the planned compact
range table list.
plan nodes, so that the executor does not need to get these items from
the range table at runtime. This will avoid needing to include these
fields in the compact range table I'm expecting to make the executor use.
portals using PORTAL_UTIL_SELECT strategy. This is currently significant only
for FETCH queries, which are supposed to include a count in the tag. Seems
it's been broken since 7.4, but nobody noticed before Knut Lehre.

equal functions are checked for raw parse trees as well as post-analysis
trees. This was never very important before, but the upcoming plan cache
control module will need to be able to do copyObject() on raw parse trees.

forces a particular relation nonnullable, then we can say that the OR does.
This is worth a little extra trouble since it may allow reduction of
outer joins to plain joins.
an opclass for a generic type such as ANYARRAY. The original coding failed
to check that PK and FK columns were of the same array type. Per discussion
with Tom Dunstan. Also, make the code a shade more readable by not trying
to economize on variables.
JOIN quals, just like WHERE quals, even if they reference every one of the
join's relations. Now that we can reorder outer and inner joins, it's
possible for such a qual to end up being assigned to an outer join plan node,
and we mustn't have it treated as a join qual rather than a filter qual for
the node. (If it were, the join could produce null-extended rows that it
shouldn't.) Per bug report from Pelle Johansson.
be checked at plan levels below the top; namely, we have to allow for Result
nodes inserted just above a nestloop inner indexscan. Should think about
using the general Param mechanism to pass down outer-relation variables, but
for the moment we need a back-patchable solution. Per report from Phil Frost.
to_timestamp():
- ID for day-of-week
- IDDD for day-of-year
This makes it possible to convert ISO week dates to and from text
fully represented in either week ('IYYY-IW-ID') or day-of-year
('IYYY-IDDD') format.
I have also added an 'isoyear' field for use with extract / date_part.
