They are so small that it makes sense to do it like that. Here's a
patch for this.
I have also changed things so that:
1. test modules are not installed by "make install", not checked by
"make installcheck", not checked by "make check".
2. test modules are checked by "make check-world" (this is consistent
with handling of contrib).
3. test modules are checked by "make installcheck-world" (this is
consistent with handling of contrib)
4. test modules are installed by "make install-world". This is
consistent with contrib, and it's necessary so that "make
installcheck-world" passes.
I moved the contents from SGML files into READMEs, and removed the
references from other SGML files, turning them into
<filename>contrib/</> instead (these are release-9.4 and so on, which is
why I reference the old locations. I assume release-9.5 will mention
the moves).
There's some untested new code in vcregress.pl, but nothing else
about msvc has been done.

+=========
+
+The SECURITY LABEL statement allows the user to assign security

+
+Security label providers intended to be used in production will typically be

+test_decoding is an example of a logical decoding
+output plugin. It doesn't do anything especially useful, but can serve as
+a starting point for developing your own decoder.
+
+test_decoding receives WAL through the logical decoding
+mechanism and decodes it into text representations of the operations
+performed.
+
+Typical output from this plugin, used over the SQL logical decoding
+interface, might be:
+
+postgres=# SELECT * FROM pg_logical_slot_get_changes('test_slot', NULL, NULL, 'include-xids', '0');

+test_parser is an example of a custom parser for full-text
+search. It doesn't do anything especially useful, but can serve as
+a starting point for developing your own parser.
+
+test_parser recognizes words separated by white space,
+and returns just two token types:
+
+mydb=# SELECT * FROM ts_token_type('testparser');
+ tokid | alias | description
+-------+-------+---------------
+ 3 | word | Word
+ 12 | blank | Space symbols
+(2 rows)
+
+These token numbers have been chosen to be compatible with the default
+parser's numbering. This allows us to use its headline()
+function, thus keeping the example simple.
+
+Usage
+=====
+
+Installing the test_parser extension creates a text search
+parser testparser. It has no user-configurable parameters.
+
+You can test the parser with, for example,
+
+mydb=# SELECT * FROM ts_parse('testparser', 'That''s my first own parser');
+ tokid | token
+-------+--------
+ 3 | That's
+ 12 |
+ 3 | my
+ 12 |
+ 3 | first
+ 12 |
+ 3 | own
+ 12 |
+ 3 | parser
+
+Real-world use requires setting up a text search configuration
+that uses the parser. For example,
+
+mydb=# CREATE TEXT SEARCH CONFIGURATION testcfg ( PARSER = testparser );
+CREATE TEXT SEARCH CONFIGURATION
+
+mydb=# ALTER TEXT SEARCH CONFIGURATION testcfg
+mydb-# ADD MAPPING FOR word WITH english_stem;
+ALTER TEXT SEARCH CONFIGURATION
+
+mydb=# SELECT to_tsvector('testcfg', 'That''s my first own parser');
+ to_tsvector
+-------------------------------
+ 'that':1 'first':3 'parser':5
+(1 row)
+
+mydb=# SELECT ts_headline('testcfg', 'Supernovae stars are the brightest phenomena in galaxies',
+mydb(# to_tsquery('testcfg', 'star'));
+ ts_headline
+-----------------------------------------------------------------
+ Supernovae <b>stars</b> are the brightest phenomena in galaxies
+(1 row)

+test_shm_mq is an example of how to use dynamic shared memory
+and the shared memory message queue facilities to coordinate a user backend
+with the efforts of one or more background workers. It is not intended to
+do anything useful on its own; rather, it is a demonstration of how these
+facilities can be used, and a unit test of those facilities.
+
+The function is this extension send the same message repeatedly through
+a loop of processes. The message payload, the size of the message queue
+through which it is sent, and the number of processes in the loop are
+configurable. At the end, the message may be verified to ensure that it
+has not been corrupted in transmission.
+
+Functions
+=========
+
+
+test_shm_mq(queue_size int8, message text,
+ repeat_count int4 default 1, num_workers int4 default 1)
+ RETURNS void
+
+This function sends and receives messages synchronously. The user
+backend sends the provided message to the first background worker using
+a message queue of the given size. The first background worker sends
+the message to the second background worker, if the number of workers
+is greater than one, and so forth. Eventually, the last background
+worker sends the message back to the user backend. If the repeat count
+is greater than one, the user backend then sends the message back to
+the first worker. Once the message has been sent and received by all
+the coordinating processes a number of times equal to the repeat count,
+the user backend verifies that the message finally received matches the
+one originally sent and throws an error if not.
+
+
+test_shm_mq_pipelined(queue_size int8, message text,
+ repeat_count int4 default 1, num_workers int4 default 1,
+ verify bool default true)
+ RETURNS void
+
+This function sends the same message multiple times, as specified by the
+repeat count, to the first background worker using a queue of the given
+size. These messages are then forwarded to each background worker in
+turn, in each case using a queue of the given size. Finally, the last
+background worker sends the messages back to the user backend. The user
+backend uses non-blocking sends and receives, so that it may begin receiving
+copies of the message before it has finished sending all copies of the
+message. The 'verify' argument controls whether or not the
+received copies are checked against the message that was sent. (This
+takes nontrivial time so it may be useful to disable it for benchmarking
+purposes.)
