Initial version of Postgres 9.4 release notes
Add missing 9.4 release file.
Replace SYSTEMQUOTEs with Windows-specific wrapper functions.

It's easy to forget using SYSTEMQUOTEs when constructing command strings
for system() or popen(). Even if we fix all the places missing it now, it is
bound to be forgotten again in the future. Introduce wrapper functions that
do the the extra quoting for you, and get rid of SYSTEMQUOTEs in all the
callers.

We previosly used SYSTEMQUOTEs in all the hard-coded command strings, and
this doesn't change the behavior of those. But user-supplied commands, like
archive_command, restore_command, COPY TO/FROM PROGRAM calls, as well as
pgbench's \shell, will now gain an extra pair of quotes. That is desirable,
but if you have existing scripts or config files that include an extra
pair of quotes, those might need to be adjusted.

Assert that pre/post-fix updated tuples are on the same page during replay.

If they were not 'oldtup.t_data' would be dereferenced while set to NULL
in case of a full page image for block 0.

Do so primarily to silence coverity; but also to make sure this prerequisite
isn't changed without adapting the replay routine as that would appear to
work in many cases.

Use Size instead of uint32 to store result of sizeof()

Silences coverity and is more consistent with other functions in the
same file.

Don't leak memory after connection aborts in pg_recvlogical.

Andres Freund, noticed by coverity.
Pass sensible value to memset() when randomizing reorderbuffer's tuple slab.

This is entirely harmless, but still wrong. Noticed by coverity.

Update 9.4 release notes with feedback from the hackers list
Update "huge pages" description in the 9.4 release notes
Fix case of pg_dump -Fc to an unseekable file (such as a pipe).

This was accidentally broken in commits cfa1b4a711/5e8e794e3b.
It saves a line or so to call ftello unconditionally in _CloseArchive,
but we have to expect that it might fail if we're not in hasSeek mode.
Per report from Bernd Helmle.

In passing, improve _getFilePos to print an appropriate message if
ftello fails unexpectedly, rather than just a vague complaint about
"ftell mismatch".
