Internally, we have supported the option to either wait for all of the
WAL associated with a backup to be archived, or to return immediately.
This option is useful to users of pg_stop_backup() as well, when they
are reading the stop backup record position and checking that the WAL
they need has been archived independently.
This patch adds an additional, optional, argument to pg_stop_backup()
which allows the user to indicate if they wish to wait for the WAL to be
archived or not. The default matches current behavior, which is to
wait.

Previously AELs were registered against the top-level xid, which could
cause locks to be held much longer than necessary in some cases during
Hot Standby replay. We now record locks directly against their appropriate
xids. Requires few code changes because original code allowed for this
situation but didn’t fully implement it.

Logical replication no longer uses the "replication" keyword. It just
matches database entries in the normal way. The "replication" keyword

A hot standby replica keeps a list of Access Exclusive locks for a top
level transaction. These locks are released when the top level transaction
ends. Searching of this list is O(N^2), and each transaction had to pay the
price of searching this list for locks, even if it didn't take any AE
locks itself.
This patch optimizes this case by having the master server track which
transactions took AE locks, and passes that along to the standby server in
the commit/abort record. This allows the standby to only try to release
locks for transactions which actually took any, avoiding the majority of
the performance issue.

Uses page-based mechanism to ensure we’re using the correct timeline.
Tests are included to exercise the functionality using a cold disk-level copy

intended use of the functionality is with later features.

Partitioned tables do not contain any data; only their unpartitioned
descendents need to be scanned. However, the partitioned tables still
need to be locked, even though they're not scanned. To make that
work, Append and MergeAppend relations now need to carry a list of
(unscanned) partitioned relations that must be locked, and InitPlan
must lock all partitioned result relations.
Aside from the obvious advantage of avoiding some work at execution
time, this has two other advantages. First, it may improve the
planner's decision-making in some cases since the empty relation
might throw things off. Second, it paves the way to getting rid of
the storage for partitioned tables altogether.

The current DirectFunctionCall functions use NULL as the flinfo in
initializing the FunctionCallInfoData for the call. That means the
called function has no fn_mcxt or fn_extra to work with, and attempting
to do so will result in an access violation. These functions instead use
the provided flinfo, which will usually be the caller's own flinfo. The
caller needs to ensure that it doesn't use the fn_extra in way that is
incompatible with the way the called function will use it. The called
function should not rely on anything else in the provided context, as it
will be relevant to the caller, not the callee.

There is still some inconsistency with the error messages surrounding
foreign servers. Some use the word "foreign" and some don't. My
inclination is to remove all such uses of "foreign" on the basis that
the CREATE/ALTER/DROP SERVER commands don't use the word. However, that
is left for another day. In this patch I have kept to the existing usage
in the affected commands, which omits "foreign".

Not every platform supports non-default collations, as pointed out by
the buildfarm, so skip collation-related regression tests in pg_dump
when they aren't supported.
The non-concurrent code path for REFRESH MATERIALIZED VIEW failed to
report its updates to the stats collector. This is bad since it means
auto-analyze doesn't know there's any work to be done. Adjust it to
report the refresh as a table truncate followed by insertion of an
appropriate number of rows.
Since a matview could contain more than INT_MAX rows, change the
signature of pgstat_count_heap_insert() to accept an int64 rowcount.
(The accumulator it's adding into is already int64, but existing
callers could not insert more than a small number of rows at once,
so the argument had been declared just "int n".)
This is surely a bug fix, but changing pgstat_count_heap_insert()'s API
seems too risky for the back branches. Given the lack of previous
complaints, I'm not sure it's a big enough problem to justify a kluge
solution that would avoid that. So, no back-patch, at least for now.
