Commit 16828d5c02 neglected to do this, so upgraded databases would
silently get null instead of the specified default in rows without the
attribute defined.
A new binary upgrade function is provided to perform this and pg_dump is
adjusted to output a call to the function if required in binary upgrade
mode.
Also included is code to drop missing attribute values for dropped
columns. That way if the type is later dropped the missing value won't
have a dangling reference to the type.
Finally the regression tests are adjusted to ensure that there is a row
with a missing value so that this code is exercised in upgrade testing.
Catalog version unfortunately bumped.
Regression test changes from Tom Lane.

Don't move parenthesized lines to the left, even if that means they
flow past the right margin.
By default, BSD indent lines up statement continuation lines that are
within parentheses so that they start just to the right of the preceding
left parenthesis. However, traditionally, if that resulted in the
continuation line extending to the right of the desired right margin,
then indent would push it left just far enough to not overrun the margin,
if it could do so without making the continuation line start to the left of
the current statement indent. That makes for a weird mix of indentations
unless one has been completely rigid about never violating the 80-column
limit.
This behavior has been pretty universally panned by Postgres developers.
Hence, disable it with indent's new -lpl switch, so that parenthesized
lines are always lined up with the preceding left paren.
This patch is much less interesting than the first round of indent
changes, but also bulkier, so I thought it best to separate the effects.

In functions that issue a deconstruct_array() call, consistently use
plain VARSIZE()/VARDATA() on the array elements. Prior practice was
divided between those and VARSIZE_ANY_EXHDR()/VARDATA_ANY().

Gen_fmgrtab.pl creates a new file fmgrprotos.h, which contains
prototypes for all functions registered in pg_proc.h. This avoids
having to manually maintain these prototypes across a random variety of
header files. It also automatically enforces a correct function
signature, and since there are warnings about missing prototypes, it
will detect functions that are defined but not registered in
pg_proc.h (or otherwise used).

Now that all of the infrastructure exists, add in the ability to
dump out the ACLs of the objects inside of pg_catalog or the ACLs
for objects which are members of extensions, but only if they have
been changed from their original values.
The original values are tracked in pg_init_privs. When pg_dump'ing
9.6-and-above databases, we will dump out the ACLs for all objects
in pg_catalog and the ACLs for all extension members, where the ACL
has been changed from the original value which was set during either
initdb or CREATE EXTENSION.
This should not change dumps against pre-9.6 databases.

The CHECK_IS_BINARY_UPGRADE macro is not sufficient security protection
if we're going to dereference pass-by-reference arguments before it.
But in any case we really need to explicitly check PG_ARGISNULL for all
the arguments of a non-strict function, not only the ones we expect null
values for.
Oversight in commits 30982be4e5019684e1772dd9170aaa53f5a8e894 and
f92fc4c95ddcc25978354a8248d3df22269201bc. Found by Andreas Seltenreich.
(The other usages in pg_upgrade_support.c seem safe.)

Previously, these functions were created in a schema "binary_upgrade",
which was deleted after pg_upgrade was finished. Because we don't want
to keep that schema around permanently, move them to pg_catalog but
rename them with a binary_upgrade_... prefix.
The provided functions are only small wrappers around global variables
that were added specifically for pg_upgrade use, so keeping the module
separate does not create any modularity.
The functions still check that they are only called in binary upgrade
mode, so it is not possible to call these during normal operation.
