walreceiver as whole into a dynamically loaded module, split the
libpq-specific parts of it into dynamically loaded module and keep the rest
in the main backend binary.
Although Tom fixed the Windows compilation problems with the old walreceiver
module already, this is a cleaner division of labour and makes the code
more readable. There's also the prospect of adding new transport methods
as pluggable modules in the future, which this patch makes easier, though for
now the API between libpqwalreceiver and walreceiver process should be
considered private.
The libpq-specific module is now in src/backend/replication/libpqwalreceiver,
and the part linked with postgres binary is in
src/backend/replication/walreceiver.c.
This includes two new kinds of postmaster processes, walsenders and
walreceiver. Walreceiver is responsible for connecting to the primary server
and streaming WAL to disk, while walsender runs in the primary server and
streams WAL from disk to the client.
Documentation still needs work, but the basics are there. We will probably
pull the replication section to a new chapter later on, as well as the
sections describing file-based replication. But let's do that as a separate
patch, so that it's easier to see what has been added/changed. This patch
also adds a new section to the chapter about FE/BE protocol, documenting the
protocol used by walsender/walreceivxer.
Bump catalog version because of two new functions,
pg_last_xlog_receive_location() and pg_last_xlog_replay_location(), for
monitoring the progress of replication.

Update install-sh to that from Autoconf 2.63, plus our Darwin-specific
changes (which I simplified a bit). install-sh is now able to install
multiple files in one run, so we could simplify our makefiles sometime.
install-sh also now has a -d option to create directories, so we don't need
mkinstalldirs anymore.
Use AC_PROG_MKDIR_P in configure.in, so we can use mkdir -p when available
instead of install-sh -d. For consistency with the rest of the world,
the corresponding make variable has been renamed from $(mkinstalldirs) to
$(MKDIR_P).
Test coverage support now covers the entire source tree, including
contrib, instead of just src/backend. In a related but independent
development, the commands make coverage and make coverage-html can be run
in any directory.
This turned out to be much easier than feared. Besides a few ad hoc fixes
to pass the make target down the tree, change all affected makefiles to
list their directories in the SUBDIRS variable, changed from variants like
DIRS and WANTED_DIRS. MSVC build fix was attempted as well.
wrappers (similar to procedural languages). This way we don't need to retain
the nearly empty libraries, and we are more free in how to implement the
wrapper API in the future.
This doesn't do any remote or external things yet, but it gives modules
like plproxy and dblink a standardized and future-proof system for
managing their connection information.

errors in any commands, including in various clean targets that have so far
been handled inconsistently. make -i is available to ignore all errors in
a consistent and official way.
Oleg Bartunov and Teodor Sigaev, but I did a lot of editorializing,
so anything that's broken is probably my fault.
Documentation is nonexistent as yet, but let's land the patch so we can
get some portability testing done.
"make pgxs install by default". It is up to the committers to chose.
(1) there is only one "install" target. no more "install-all-headers".
it simplifies/changes several makefiles.
(2) the documentation reflects the change.
(3) a minor fix on pgxs to use a nicer patch without a double slash.

Eliminate the mysterious games that the Cygwin build plays with the linker
flag variables. DLLLIBS is gone, use SHLIB_LINK like everyone else.
Detect cygipc in configure, after the linker flags are set up, otherwise
configure might not work at all.
Make sure everything is covered by make clean.
Fix the build of the new conversion procedure modules.
Add new DLLIMPORT markers where required.
Finally, the compiler complains if we use an explicit
-I/usr/local/include, so don't do that. Curiously, -L/usr/local/lib is
still necessary.
'make install'; there are enough of 'em that this slowed down the make
noticeably. Ensure that 'all' is the default make target in all these
directories (defaulting to 'make install' is surprising and dangerous
IMHO). Fix a couple small typos.
src/GNUmakefile.in to src/Makefile
and
src/backend/port/Makefile.in to src/backend/port/Makefile
All configure substitutions are now done in Makefile.global.
are now separate files "postgres.h" and "postgres_fe.h", which are meant
to be the primary include files for backend .c files and frontend .c files
respectively. By default, only include files meant for frontend use are
installed into the installation include directory. There is a new make
target 'make install-all-headers' that adds the whole content of the
src/include tree to the installed fileset, for use by people who want to
develop server-side code without keeping the complete source tree on hand.
Cleaned up a whole lot of crufty and inconsistent header inclusions.
that now functions as a wrapper around the MakeMaker stuff. It might
even behave sensically when we have separate build dirs. Same for plperl,
which of course still doesn't work very well. Made sure that plperl
respects the choice of --libdir.
Added --with-python to automatically build and install the Python interface.
Works similarly to the Perl5 stuff.
Moved the burden of the distclean targets lower down into the source tree.
Eventually, each make file should have its own.
Added automatic remaking of makefiles and configure. Currently only for the
top-level because of a bug(?) in Autoconf. Use GNU `missing' to work around
missing autoconf and aclocal. Start factoring out macros into their own
config/*.m4 files to increase readability and organization.
to be sleazy and reach into other subsystems' directories. First entry in
this directory is the PG_VERSION file interface, which must be used by the
backend and also the pg_version program (which is used by initdb).
with some versions of sh, and a bug in the master make file that
causes it to issue the message "postgres has been built" at the wrong
time.

does 2 things:
1) Make it hard to not notice the make failed. (As you recall, someone on
the mailing list had this problem. I've had it to some extent myself).
The 1.02 make files continue with the next subdirectory when a make
in a subdirectory fails. The patch makes the make stop in the
conventional way when a submake fails. It also adds a reassuring message
when the make succeeds and adds a note to the INSTALL file to expect it.
2) Include loader flags on all invocations of the linker.
The 1.02 make files omit the $(LDFLAGS) on some of the linker invocations.
On my system, I need one of those flags just to make it invoke the proper
version of the compiler/linker, so LDFLAGS has to be everywhere.
