For several operating systems, we give handy package manager one-liners
to install all the requirements for building our documentation. All
current production FreeBSD releases have a friendly new package manager
a bit like apt/yum, so give a one line command here. Also, add a brief
note about gmake vs make in the doc subdirectory.

Allows testing of logical decoding using SQL interface and/or pg_recvlogical
Most logical decoding tests are in contrib/test_decoding. This module
is for work that doesn't fit well there, like where server restarts

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".

User mappings are essentially anonymous, so messages referring to "user
mapping foo on server bar" are wrong, and inconsistent with other error
messages referring to user mappings. To be consistent with existing use,
use "user mapping for foo on server bar" instead.
I dropped the noise word "user" from the original suggestion to be
consistent with other uses.

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.

Change the header style of references pages in HTML and PDF output to be
more like the old style under DSSSL. In particular, the page should
start with a header containing the command name, instead of just "Name".
This is really testing getopt more than pg_dump, and what getopt returns
exactly appears to differ based on platform, so remove this test.
Per buildfarm.
These improvements bring the lines-of-code coverage of pg_dump.c up to
87.7% (at least using LCOV 1.12, 1.11 seems to differ slightly). Nearly
every function is covered, three of the four which aren't are only
called when talking to older PG instances.
There is more which can, and should, be done here to improve the
coverage but it's past time to see what the buildfarm thinks of this.
What has been added:
- Coverage for many more command-line options
- Use command_fails_like instead of command_exit_is
- Operator classes, operator families
- Text search configuration, templates, parsers, dictionaries
- FDWs, servers, foreign tables
- Materialized views
- Improved Publications / Subscriptions test (though this needs work,
see PG10 open items and tests marked with XXX in 002_pg_dump.pl)
- Unlogged tables
- Partitioned tables
- Additional ACL testing for various object types
There is room for improvement, specifically:
- Various type-based option (alignment, storage, etc)
- Composite type collation
- Extra Procedural language functions (inline, validator)
- Different function options (SRF, Transform, config, security definer,
cost, leakproof)
- OpClass options (default, storage, order by, recheck)
- OpFamily options (order by, recheck)
- Aggregate functions (combinefunc, serialfunc, deserialfunc, etc)
- Text Search parser 'headline'
- Text Search template 'init'
- FDW options (handler, validator, options)
- Server options (type, version, options)
- User mapping options
- Default ACLs for sequences, types
- Security labels
- View circular dependencies (last function that needs coverage)
- Toast table autovacuum options
- Replica identity options
- Independent indexes (plus marking them as clustered on)
- Deferrable / initially deferred constraints
- Independent domain constraints
There's bits of extension pg_dump'ing also not covered, but those will
need to go into test_pg_dump (such as having a filter for config
tables).
Last, but not least, this approximately halves the number of tests run
with 'ok()' by removing the ok()-based checking of if all runs are
covered by each test. Instead, 002_pg_dump.pl will just exit out in
such a case (with a message in the log file). In general, when adding
tests, cover all runs unless there is a very good reason not to (such as
adding a 'catch-all' case). With these changes, the resulting output
and number of "tests" run is actually reduced.
Previous commits, notably 53be0b1add and
6f3bd98ebf, made it possible to see from
pg_stat_activity when a backend was stuck waiting for another backend,
but it's also fairly common for a backend to be stuck waiting for an
I/O. Add wait events for those operations, too.

Windows apparently will not detect socket write-ready events unless a
preceding send attempt returned WSAEWOULDBLOCK. In many usage patterns
that's satisfied by the caller of WaitEvenSetWait(), but not always.
Apply the same solution that we already had in pgwin32_select(), namely to
perform a dummy WSASend() call with len=0. This will return WSAEWOULDBLOCK
if there's no buffer space (even though it could legitimately do nothing
and report success, which makes me a bit nervous about this solution;
but since it's been working fine in libpq, let's roll with it).
In passing, improve the comments about this in pgwin32_select(), and remove
duplicated code there.
Back-patch to 9.6 where WaitEventSetWait() was introduced. We might need
to back-patch something similar into predecessor code. But given the lack
of complaints so far, it's not clear that the case ever gets exercised
in the back branches, so I'm not going to expend effort on it right now.
This should resolve recurring failures on buildfarm member bowerbird,
which has been failing since 1e8a85009 went in.
