place to prevent reusing relation OIDs before next checkpoint, and DROP
DATABASE. First, if a database was dropped, bgwriter would still try to unlink
the files that the rmtree() call by the DROP DATABASE command has already
deleted, or is just about to delete. Second, if a database is dropped, and
another database is created with the same OID, bgwriter would in the worst
case delete a relation in the new database that happened to get the same OID
as a dropped relation in the old database.
To fix these race conditions:
- make rmtree() ignore ENOENT errors. This fixes the 1st race condition.
- make ForgetDatabaseFsyncRequests forget unlink requests as well.
- force checkpoint on in dropdb on all platforms
Since ForgetDatabaseFsyncRequests() is asynchronous, the 2nd change isn't
enough on its own to fix the problem of dropping and creating a database with
same OID, but forcing a checkpoint on DROP DATABASE makes it sufficient.

Per report and research by Sergey Zubkovsky.
The places that did, eg,
(statbuf.st_mode & S_IFMT) == S_IFDIR
were correct, but there is no good reason not to use S_ISDIR() instead,
especially when that's what the other 90% of our code does. The places
that did, eg,
(statbuf.st_mode & S_IFDIR)
were flat out *wrong* and would fail in various platform-specific ways,
eg a symlink could be mistaken for a regular file on most Unixen.
The actual impact of this is probably small, since the problem cases
seem to always involve symlinks or sockets, which are unlikely to be
found in the directories that PG code might be scanning. But it's
clearly trouble waiting to happen, so patch all the way back anyway.

This removes the direct dependency on shell32.dll and user32.dll, which
eats a lot of "desktop heap" for each backend that's started. The

After updating to the latest cvs, and also building most of the addons

* Switch to use the new win32 semaphore code
* Rename win32_open to pgwin32_open. win32_open collides with symbols
defined in Perl. MingW didn't detect ig, MSVC did. And it's a bit too

backend, etc. We now longjmp only from calls to readline, fgets, and

the logic it contained to switch to insertion sort for near-sorted input was
in fact a big loss, because it could fairly easily be fooled into applying
insertion sort to large subfiles that weren't all that well ordered. Remove
that, and instead add a simple check for already-perfectly-sorted input, as
per suggestion from Dann Corbit. This adds at worst O(N*lgN) overhead, and
usually far less, while sometimes allowing a subfile sort to finish in O(N)
time. Preliminary testing says this is an improvement over the basic
Bentley & McIlroy code for many nonrandom inputs, and it costs almost
nothing when the input is random.

that they match up to the last component, accept whatever common prefix
they have, and try to replace the non-matching part of bin_path with
the non-matching part of target_path in the actual executable's path.
In one way this is tighter than the old code, because it insists on
a match to the part of bin_path we want to substitute for, rather than
blindly stripping one directory component from the executable's path.

of special case for Windows port. Put a PG_TRY around most of createdb()

failure happens while creating the pg_database row. (I think this explains
Oliver Siegmar's recent report.) Having done that, there's no need for
the fragile assumption that copydir() mustn't ereport(ERROR), so simplify
its API. Eliminate the old code that used system("cp ...") to copy
subdirectories, in favor of using copydir() on all platforms. This not
only should allow much better error reporting, but allows us to fsync
the created files before trusting that the copy has succeeded.
The first rule of portability for us is 'thou shalt have no other gods

extensive change then what was suggested. I found the file path.c that
contained a lot of "Unix/Windows" agnostic functions so I added a function
there instead and removed the PATHSEP declaration in exec.c altogether. All
to keep things from scattering all over the code.
I also took the liberty of changing the name of the functions
"first_path_sep" and "last_path_sep". Where I come from (and I'm apparently
not alone given the former macro name PATHSEP), they should be called
"first_dir_sep" and "last_dir_sep". The new function I introduced, that
actually finds path separators, is now the "first_path_sep". The patch
contains changes on all affected places of course.
I also changed the documentation on dynamic_library_path to reflect the
chagnes.

the calling program, and checks the version string.
The only behavior change was that initdb and pg_dump would look in the
hard-coded bindir directory if it can't find the requested binary in the

remove most but not all direct uses of toupper and tolower in favor of
pg_toupper and pg_tolower. These functions use the same notions of
case folding already developed for identifier case conversion. I left
the straight locale-based folding in place for situations where we are
just manipulating user data and not trying to match it to built-in
strings --- for example, the SQL upper() function is still locale
dependent. Perhaps this will prove not to be what's wanted, but at
the moment we can initdb and pass regression tests in Turkish locale.

It works on the principle of turning sockets into non-blocking, and then
emulate blocking behaviour on top of that, while allowing signals to
run. Signals are now implemented using an event instead of APCs, thus
getting rid of the issue of APCs not being compatible with "old style"
sockets functions.
It also moves the win32 specific code away from pqsignal.h/c into
port/win32, and also removes the "thread style workaround" of the APC
issue previously in place.
In order to make things work, a few things are also changed in pgstat.c:
1) There is now a separate pipe to the collector and the bufferer. This
is required because the pipe will otherwise only be signalled in one of
the processes when the postmaster goes down. The MS winsock code for
select() must have some kind of workaround for this behaviour, but I
have found no stable way of doing that. You really are not supposed to
use the same socket from more than one process (unless you use
WSADuplicateSocket(), in which case the docs specifically say that only
one will be flagged).
2) The check for "postmaster death" is moved into a separate select()
call after the main loop. The previous behaviour select():ed on the
postmaster pipe, while later explicitly saying "we do NOT check for
postmaster exit inside the loop".
The issue was that the code relies on the same select() call seeing both
the postmaster pipe *and* the pgstat pipe go away. This does not always
happen, and it appears that useing WSAEventSelect() makes it even more
common that it does not.
Since it's only called when the process exits, I don't think using a
separate select() call will have any significant impact on how the stats
collector works.
