as determined by include-what-you-use (IWYU)
While IWYU also suggests to *add* a bunch of #include's (which is its
main purpose), this patch does not do that. In some cases, a more
specific #include replaces another less specific one.
Some manual adjustments of the automatic result:
- IWYU currently doesn't know about includes that provide global
variable declarations (like -Wmissing-variable-declarations), so
those includes are being kept manually.
- All includes for port(ability) headers are being kept for now, to
play it safe.
- No changes of catalog/pg_foo.h to catalog/pg_foo_d.h, to keep the
patch from exploding in size.
Note that this patch touches just *.c files, so nothing declared in
header files changes in hidden ways.
As a small example, in src/backend/access/transam/rmgr.c, some IWYU
pragma annotations are added to handle a special case there.

This is mostly straightforward, except that if the range type
has a canonical function, that might throw an error during range
input. (Such errors probably only occur for edge cases: in the
in-core canonical functions, it happens only if a bound has the
maximum valid value for the underlying type.) Hence, this patch
extends the soft-error regime to allow canonical functions to
return errors softly as well. Extensions implementing range
canonical functions will need modification anyway because of the
API change for range_serialize(); while at it, they might want
to do something similar to what's been done here in the in-core
canonical functions.

Since these macros just cast whatever you give them to the designated
output type, and many normal uses also cast the output type further, a
number of incorrect uses go undiscovered. The fixes in this patch
have been discovered by changing these macros to inline functions,
which is the subject of a future patch.

There were a number of places in the code that used bespoke bit-twiddling
expressions to do bitwise rotation. While we've had pg_rotate_right32()
for a while now, we hadn't gotten around to standardizing on that. Do so
now. Since many potential call sites look more natural with the "left"
equivalent, add that function too.

The multirange_get_range() function fails when two boundaries of the same
range have different alignments. Fix that by adding proper pointer alignment.

Backpatch-through: 14
It has been spotted that multiranges lack of ability to decompose them into
individual ranges. Subscription and proper expanded object representation
require substantial work, and it's too late for v14. This commit
provides the implementation of unnest(multirange), which is quite trivial.
unnest(multirange) is defined as a polymorphic procedure.
Catversion is bumped.

Braces were referred in some error messages as only brackets (not curly
brackets or curly braces), which can be confusing as other types of
brackets could be used.
While on it, add one test to check after the case of junk characters
detected after a right brace.

These functions shouldn't receive null arguments: multirange_constructor0()
doesn't have any arguments while multirange_constructor2() has a single array
argument, which is never null.
But mark them strict anyway for the sake of uniformity.
Also, make checks for null arguments use elog() instead of ereport() as these
errors should normally be never thrown. And adjust corresponding comments.

6df7a9698b has introduced a set of operators between ranges and multiranges.
Existing GiST indexes for ranges could easily support majority of them.
This commit adds support for new operators to the existing range GiST indexes.
New operators resides the same strategy numbers as existing ones. Appropriate
check function is determined using the subtype.

There is a set of *_internal() functions exposed in
include/utils/multirangetypes.h. This commit improves the signatures of these
functions in two ways.
* Add const qualifies where applicable.
* Replace multirange typecache argument with range typecache argument.
Multirange typecache was used solely to find the range typecache. At the
same time, range typecache is easier for the caller to find.
We have operators for checking if the multirange contains a range but don't
have the opposite. This commit improves completeness of the operator set by
adding two new operators: @> (anyrange,anymultirange) and
<@(anymultirange,anyrange).
Catversion is bumped.
Two functions multirange_range_overlaps_bsearch_comparison() and
multirange_range_contains_bsearch_comparison() contain bugs of returning -1
instead of 1. This commit fixes these bugs and adds corresponding regression
tests.
Multiranges are basically sorted arrays of non-overlapping ranges with
set-theoretic operations defined over them.
Since v14, each range type automatically gets a corresponding multirange
datatype. There are both manual and automatic mechanisms for naming multirange
types. Once can specify multirange type name using multirange_type_name
attribute in CREATE TYPE. Otherwise, a multirange type name is generated
automatically. If the range type name contains "range" then we change that to
"multirange". Otherwise, we add "_multirange" to the end.
Implementation of multiranges comes with a space-efficient internal
representation format, which evades extra paddings and duplicated storage of
oids. Altogether this format allows fetching a particular range by its index
in O(n).
Statistic gathering and selectivity estimation are implemented for multiranges.
For this purpose, stored multirange is approximated as union range without gaps.
This field will likely need improvements in the future.
