While user-defined triggers defined on a partitioned table have
a catalog definition for both it and its partitions, internal
triggers used by foreign keys defined on partitioned tables only
have a catalog definition for its partitions. This commit fixes
that so that partitioned tables get the foreign key triggers too,
just like user-defined triggers. Moreover, like user-defined
triggers, partitions' internal triggers will now also have their
tgparentid set appropriately. This is to allow subsequent commit(s)
to make the foreign key related events to be fired in some cases
using the parent table triggers instead of those of partitions'.
This also changes what tgisinternal means in some cases. Currently,
it means either that the trigger is an internal implementation object
of a foreign key constraint, or a "child" trigger on a partition
cloned from the trigger on the parent. This commit changes it to
only mean the former to avoid confusion. As for the latter, it can
be told by tgparentid being nonzero, which is now true both for user-
defined and foreign key's internal triggers.

Commit 4ace45677 failed to fix the problem fully, because the
same issue of attempting to fetch a non-returnable index column
can occur when rechecking the indexqual after using a lossy index
operator. Moreover, it broke EXPLAIN for such indexquals (which
indicates a gap in our test cases :-().
Revert the code changes of 4ace45677 in favor of adding a new field
to struct IndexOnlyScan, containing a version of the indexqual that
can be executed against the index-returned tuple without using any
non-returnable columns. (The restrictions imposed by check_index_only
guarantee this is possible, although we may have to recompute indexed
expressions.) Support construction of that during setrefs.c
processing by marking IndexOnlyScan.indextlist entries as resjunk
if they can't be returned, rather than removing them entirely.
(We could alternatively require setrefs.c to look up the IndexOptInfo
again, but abusing resjunk this way seems like a reasonably safe way
to avoid needing to do that.)
This solution isn't great from an API-stability standpoint: if there
are any extensions out there that build IndexOnlyScan structs directly,
they'll be broken in the next minor releases. However, only a very
invasive extension would be likely to do such a thing. There's no
change in the Path representation, so typical planner extensions
shouldn't have a problem.
As before, back-patch to all supported branches.

If an index has both returnable and non-returnable columns, and one of
the non-returnable columns is an expression using a Var that is in a
returnable column, then a query returning that expression could result
in an index-only scan plan that attempts to read the non-returnable
column, instead of recomputing the expression from the returnable
column as intended.
To fix, redefine the "indextlist" list of an IndexOnlyScan plan node
as containing null Consts in place of any non-returnable columns.
This solves the problem by preventing setrefs.c from falsely matching
to such entries. The executor is happy since it only cares about the
exposed types of the entries, and ruleutils.c doesn't care because a
correct plan won't reference those entries. I considered some other
ways to prevent setrefs.c from doing the wrong thing, but this way
seems good since (a) it allows a very localized fix, (b) it makes
the indextlist structure more compact in many cases, and (c) the
indextlist is now a more faithful representation of what the index AM
will actually produce, viz. nulls for any non-returnable columns.
This is easier to hit since we introduced included columns, but it's
possible to construct failing examples without that, as per the
added regression test. Hence, back-patch to all supported branches.

Our previous validator used a traditional algorithm that performed
comparison and branching one byte at a time. It's useful in that
we always know exactly how many bytes we have validated, but that
precision comes at a cost. Input validation can show up prominently
in profiles of COPY FROM, and future improvements to COPY FROM such
as parallelism or faster line parsing will put more pressure on input
validation. Hence, add fast paths for both ASCII and multibyte UTF-8:
Use bitwise operations to check 16 bytes at a time for ASCII. If
that fails, use a "shift-based" DFA on those bytes to handle the
general case, including multibyte. These paths are relatively free
of branches and thus robust against all kinds of byte patterns. With
these algorithms, UTF-8 validation is several times faster, depending
on platform and the input byte distribution.
The previous coding in pg_utf8_verifystr() is retained for short
strings and for when the fast path returns an error.

pg_strtouint64() is a wrapper around strtoull/strtoul/_strtoui64, but
it seems no longer necessary to have this indirection.
msvc/Solution.pm claims HAVE_STRTOULL, so the "MSVC only" part seems
unnecessary. Also, we have code in c.h to substitute alternatives for
strtoull() if not found, and that would appear to cover all currently
supported platforms, so having a further fallback in pg_strtouint64()
seems unnecessary.
Therefore, we could remove pg_strtouint64(), and use strtoull()
directly in all call sites. However, it seems useful to keep a
separate notation for parsing exactly 64-bit integers, matching the
type definition int64/uint64. For that, add new macros strtoi64() and
strtou64() in c.h as thin wrappers around strtol()/strtoul() or
strtoll()/stroull(). This makes these functions available everywhere
instead of just in the server code, and it makes the function naming
notably different from the pg_strtointNN() functions in numutils.c,
which have a different API.

It's not great that RecoveryInProgress() calls InitXLOGAccess(),
because a status inquiry function typically shouldn't have the side
effect of performing initializations. We could fix that by calling
InitXLOGAccess() from some other place, but instead, let's remove it
altogether.
One thing InitXLogAccess() did is initialize wal_segment_size, but it
doesn't need to do that. In the postmaster, PostmasterMain() calls
LocalProcessControlFile(), and all child processes will inherit that
value -- except in EXEC_BACKEND bulds, but then each backend runs
SubPostmasterMain() which also calls LocalProcessControlFile().
The other thing InitXLOGAccess() did is update RedoRecPtr and
doPageWrites, but that's not critical, because all code that uses
them will just retry if it turns out that they've changed. The
only difference is that most code will now see an initial value that
is definitely invalid instead of one that might have just been way
out of date, but that will only happen once per backend lifetime,
so it shouldn't be a big deal.

Historically we've put type "char" into the S (String) typcategory,
although calling it a string is a stretch considering it can only
store one byte. (In our actual usage, it's more like an enum.)
This choice now seems wrong in view of the special heuristics
that parse_func.c and parse_coerce.c have for TYPCATEGORY_STRING:
it's not a great idea for "char" to have those preferential casting
behaviors.
Worse than that, recent patches inventing special-purpose types
like pg_node_tree have assigned typcategory S to those types,
meaning they also get preferential casting treatment that's designed
on the assumption that they can hold arbitrary text.
To fix, invent a new category TYPCATEGORY_INTERNAL for internal-use
types, and assign that to all these types. I used code 'Z' for
lack of a better idea ('I' was already taken).
This change breaks one query in psql/describe.c, which now needs to
explicitly cast a catalog "char" column to text before concatenating
it with an undecorated literal. Also, a test case in contrib/citext
now needs an explicit cast to convert citext to "char". Since the
point of this change is to not have "char" be a surprisingly-available
cast target, these breakages seem OK.

2. Remove non-working code that was trying to do something similar for

stat() also gains resilience against "sharing violation" errors.
3. Since stat() is used very early in process startup, remove the

The term "super-exclusive lock" is a synonym for "buffer cleanup lock"
that first appeared in nbtree many years ago. Standardize things by
consistently using the term cleanup lock. This finishes work started by
commit 276db875.
There is no good reason to have two terms. But there is a good reason
to only have one: to avoid confusion around why VACUUM acquires a full
cleanup lock (not just an ordinary exclusive lock) in index AMs, during
ambulkdelete calls. This has nothing to do with protecting the physical
index data structure itself. It is needed to implement a locking
protocol that ensures that TIDs pointing to the heap/table structure
cannot get marked for recycling by VACUUM before it is safe (which is
somewhat similar to how VACUUM uses cleanup locks during its first heap
pass). Note that it isn't strictly necessary for index AMs to implement
this locking protocol -- several index AMs use an MVCC snapshot as their
sole interlock to prevent unsafe TID recycling.
In passing, update the nbtree README. Cleanly separate discussion of
the aforementioned index vacuuming locking protocol from discussion of
the "drop leaf page pin" optimization added by commit 2ed5b87f. We now
structure discussion of the latter by describing how individual index
scans may safely opt out of applying the standard locking protocol (and
so can avoid blocking progress by VACUUM). Also document why the
optimization is not safe to apply during nbtree index-only scans.

Memoize would always use the hash equality operator for the cache key
types to determine if the current set of parameters were the same as some
previously cached set. Certain types such as floating points where -0.0
and +0.0 differ in their binary representation but are classed as equal by
the hash equality operator may cause problems as unless the join uses the
same operator it's possible that whichever join operator is being used
would be able to distinguish the two values. In which case we may
accidentally return in the incorrect rows out of the cache.
To fix this here we add a binary mode to Memoize to allow it to the
current set of parameters to previously cached values by comparing
bit-by-bit rather than logically using the hash equality operator. This
binary mode is always used for LATERAL joins and it's used for normal

collation is C. (This works just like "textcol LIKE 'foo%'".)
* "starts_with(textcol, constant)" can be optimized the same as
"textcol ^@ constant".
* Fixed-prefix LIKE and regex patterns are now more like starts_with()
in another way: if you apply one to an SPGiST-indexed column, you'll
