Commit 5ac0d9360 failed to entirely fix bitshiftright's habit of
leaving one-bits in the pad space that should be all zeroes,
because in a moment of sheer brain fade I'd concluded that only
the code path used for not-a-multiple-of-8 shift distances needed
to be fixed. Of course, a multiple-of-8 shift distance can also
cause the problem, so we need to forcibly zero the extra bits
in both cases.

Encoding conversion uses the very simplistic rule that the output
can't be more than 4X longer than the input, and palloc's a buffer
of that size. This results in failure to convert any string longer
than 1/4 GB, which is becoming an annoying limitation.
As a band-aid to improve matters, allow the allocated output buffer
size to exceed 1GB. We still insist that the final result fit into
MaxAllocSize (1GB), though. Perhaps it'd be safe to relax that
restriction, but it'd require close analysis of all callers, which
is daunting (not least because external modules might call these
functions). For the moment, this should allow a 2X to 4X improvement
in the longest string we can convert, which is a useful gain in
return for quite a simple patch.
Also, once we have successfully converted a long string, repalloc
the output down to the actual string length, returning the excess
to the malloc pool. This seems worth doing since we can usually
expect to give back several MB if we take this path at all.
This still leaves much to be desired, most notably that the assumption
that MAX_CONVERSION_GROWTH == 4 is very fragile, and yet we have no
guard code verifying that the output buffer isn't overrun. Fixing
that would require significant changes in the encoding conversion
APIs, so it'll have to wait for some other day.
The present patch seems safely back-patchable, so patch all supported
branches.

Up to now, if you resized a large (>8K) palloc chunk down to a smaller
size, aset.c made no attempt to return any space to the malloc pool.
That's unpleasant if a really large allocation is resized to a
significantly smaller size. I think no such cases existed when this
code was designed, and I'm not sure whether they're common even yet,
but an upcoming fix to encoding conversion will certainly create such
cases. Therefore, fix AllocSetRealloc so that it gives realloc()
a chance to do something with the block. This doesn't noticeably
increase complexity, we mostly just have to change the order in which
the cases are considered.

If the bitstring length is not a multiple of 8, we'd shift the
rightmost bits into the pad space, which must be zeroes --- bit_cmp,
for one, depends on that. This'd lead to the result failing to
compare equal to what it should compare equal to, as reported in
bug #16013 from Daryl Waycott.
This is, if memory serves, not the first such bug in the bitstring
functions. In hopes of making it the last one, do a bit more work
than minimally necessary to fix the bug:
* Add assertion checks to bit_out() and varbit_out() to complain if
they are given incorrectly-padded input. This will improve the
odds that manual testing of any new patch finds problems.
* Encapsulate the padding-related logic in macros to make it
easier to use.
Also, remove unnecessary padding logic from bit_or() and bitxor().
Somebody had already noted that we need not re-pad the result of
bit_and() since the inputs are required to be the same length,
but failed to extrapolate that to the other two.
Also, move a comment block that once was near the head of varbit.c
(but people kept putting other stuff in front of it), to put it in
the header block.
Note for the release notes: if anyone has inconsistent data as a
result of saving the output of bitshiftright() in a table, it's
possible to fix it with something like
UPDATE mytab SET bitcol = ~(~bitcol) WHERE bitcol != ~(~bitcol);

After an unexpected connection loss and successful reconnection,
psql neglected to resynchronize its internal state about the server,
such as server version. Ordinarily we'd be reconnecting to the same
server and so this isn't really necessary, but there are scenarios
where we do need to update --- one example is where we have a list
of possible connection targets and they're not all alike.
Define "resynchronize" as including connection_warnings(), so that
this case acts the same as \connect. This seems useful; for example,
if the server version did change, the user might wish to know that.
An attuned user might also notice that the new connection isn't
SSL-encrypted, for example, though this approach isn't especially
in-your-face about such changes. Although this part is a behavioral
change, it only affects interactive sessions, so it should not break
any applications.
Also, in do_connect, make sure that we desynchronize correctly when
abandoning an old connection in non-interactive mode.
These problems evidently are the result of people patching only one
of the two places where psql deals with connection changes, so insert
some cross-referencing comments in hopes of forestalling future bugs
of the same ilk.
Lastly, in Windows builds, issue codepage mismatch warnings only at
startup, not during reconnections. psql's codepage can't change
during a reconnect, so complaining about it again seems like useless
noise.

The comment did not match what the code actually did for integers with
the 43rd bit set. You get an integer like that, if you have a posting
list with two adjacent TIDs that are more than 2^31 blocks apart.
According to the comment, we would store that in 6 bytes, with no
continuation bit on the 6th byte, but in reality, the code encodes it
using 7 bytes, with a continuation bit on the 6th byte as normal.
The decoding routine also handled these 7-byte integers correctly, except
for an overflow check that assumed that one integer needs at most 6 bytes.
Fix the overflow check, and fix the comment to match what the code
actually does. Also fix the comment that claimed that there are 17 unused
bits in the 64-bit representation of an item pointer. In reality, there
are 64-32-11=21.
Fitting any item pointer into max 6 bytes was an important property when
this was written, because in the old pre-9.4 format, item pointers were
stored as plain arrays, with 6 bytes for every item pointer. The maximum
of 6 bytes per integer in the new format guaranteed that we could convert
any page from the old format to the new format after upgrade, so that the
new format was never larger than the old format. But we hardly need to
worry about that anymore, and running into that problem during upgrade,
where an item pointer is expanded from 6 to 7 bytes such that the data
doesn't fit on a page anymore, is implausible in practice anyway.

This also includes a little test module to test these large distances
between item pointers, without requiring a 16 TB table. It is not

ALTER SYSTEM itself normally won't make duplicate entries (although
up till this patch, it was possible to confuse it by writing case
variants of a GUC's name). However, if some external tool has appended
entries to the file, that could result in duplicate entries for a single
GUC name. In such a situation, ALTER SYSTEM did exactly the wrong thing,
because it replaced or removed only the first matching entry, leaving
the later one(s) still there and hence still determining the active value.
This patch fixes that by making ALTER SYSTEM sweep through the file and
remove all matching entries, then (if not ALTER SYSTEM RESET) append the
new setting to the end. This means entries will be in order of last
setting rather than first setting, but that shouldn't hurt anything.

contrib/intarray considers "arraycol <@ constant-array" to be indexable,
but its GiST opclass code fails to reliably find index entries for empty
array values (which of course should trivially match such queries).
This is because the test condition to see whether we should descend
through a non-leaf node is wrong.
Unfortunately, empty array entries could be anywhere in the index,
as these index opclasses are currently designed. So there's no way
to fix this except by lobotomizing <@ indexscans to scan the whole
index ... which is what this patch does. That's pretty unfortunate:
the performance is now actually worse than a seqscan, in most cases.
We'd be better off to remove <@ from the GiST opclasses entirely,
and perhaps a future non-back-patchable patch will do so.
In the meantime, applications whose performance is adversely impacted
have a couple of options. They could switch to a GIN index, which
doesn't have this bug, or they could replace "arraycol <@ constant-array"
with "arraycol <@ constant-array AND arraycol && constant-array".
That will provide about the same performance as before, and it will find
all non-empty subsets of the given constant-array, which is all that
could reliably be expected of the query before.
While at it, add some more regression test cases to improve code
coverage of contrib/intarray.
In passing, adjust resize_intArrayType so that when it's returning an
empty array, it uses construct_empty_array for that rather than
cowboy hacking on the input array. While the hack produces an array
that looks valid for most purposes, it isn't bitwise equal to empty
arrays produced by other code paths, which could have subtle odd
effects. I don't think this code path is performance-critical
enough to justify such shortcuts. (Back-patch this part only as far
as v11; before commit 01783ac36 we were not careful about this in
other intarray code paths either.)

Since pg_dump doesn't treat the member operators and functions of operator
classes/families (that is, the pg_amop and pg_amproc entries, not the
underlying operators/functions) as separate dumpable objects, it missed
their dependency information. I think this was safe when the code was
designed, because the default object sorting rule emits operators and
functions before opclasses, and there were no dependency types that could
mess that up. However, the introduction of range types in 9.2 broke it:
now a type can have a dependency on an opclass, allowing dependency rules
to push the opclass before the type and hence before custom operators.
Lacking any information showing that it shouldn't do so, pg_dump emitted
the objects in the wrong order.
Fix by teaching getDependencies() to translate pg_depend entries for
pg_amop/amproc rows to look like dependencies for their parent opfamily.
