Several server header files would not be installed in vpath builds
because they live in the build directory.

New header datatype/timestamp.h should be installed for server-side dev.

This can do various source code checks that are not appropriate for
either the build or the regression tests.  Currently: duplicate_oids,
SGML syntax and tabs check, NLS syntax check.

This fixes make distprep, and seems more robust in other ways as well.
Some special handling is required because errcodes.txt is needed by
some stuff in src/port, but just by src/backend as is the case for the
other generated headers.

While I'm at it, fix a few other things that were overlooked in the
original patch.

src/pl/plpgsql/src/plerrcodes.h, src/include/utils/errcodes.h, and a
big chunk of errcodes.sgml are now automatically generated from a single
file, src/backend/utils/errcodes.txt.

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.

Fujii Masao, with additional hacking by me

pg_attribute, by having genbki.pl derive the information from the various
catalog header files.  This greatly simplifies modification of the
"bootstrapped" catalogs.

This patch finally kills genbki.sh and Gen_fmgrtab.sh; we now rely entirely on
Perl scripts for those build steps.  To avoid creating a Perl build dependency
where there was not one before, the output files generated by these scripts
are now treated as distprep targets, ie, they will be built and shipped in
tarballs.  But you will need a reasonably modern Perl (probably at least
5.6) if you want to build from a CVS pull.

The changes to the MSVC build process are untested, and may well break ---
we'll soon find out from the buildfarm.

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).

The original coding was not dealing specially with this file being a symlink,
with the end result that it was not installed in VPATH builds.  Oddly enough,
the clean target does know about it ...

change build system to use only Bison.  Simplify build rules, make file names
uniform.  Don't build the token table header file where it is not needed.

file portability/instr_time.h, and add a couple more macros to eliminate
some abstraction leakage we formerly had.  Also update psql to use this
header instead of its own copy of nearly the same code.

This commit in itself is just code cleanup and shouldn't change anything.
It lays some groundwork for the upcoming function-stats patch, though.

support DTrace in the future.

Switch from using DTRACE_PROBEn macros to the dynamically generated macros.
Use "dtrace -h" to create a header file that contains the dynamically
generated macros to be used in the source code instead of the DTRACE_PROBEn
macros.  A dummy header file is generated for builds without DTrace support.

but it was missing a bunch of recently-added subdirectories.

Add tsearch subdirectory is added to Makefile to allow
compile  custom tsearch dictionary as an external module.

This reduces header file install from 8 seconds to 0.40 seconds.

just stick a list-link into struct PGnotify instead.  Result is a smaller
faster and more robust library (mainly because we reduce the number of
malloc's and free's involved in notify processing), plus less pollution
of application link-symbol namespace.

"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.

Client headers are no longer in a subdirectory, since they have been made

Internal libpq headers are in a private subdirectory.

Server headers are in a private subdirectory.  pg_config has a new option
to point there.

be lurking in the install target directory.  But don't zap up-to-date

Per suggestion from Larry Rosenman.

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.

source directory.  This involves mostly makefiles using $(srcdir) when they
might have used ".".  (Regression tests don't work with this, yet.)

Sort out usage of CPPFLAGS, CFLAGS (and CXXFLAGS).  Add "override" keyword
in most places, to preserve necessary flags even when the user overrode the
flags.

DESTDIR=/else/where' and prepends the value of DESTDIR to the full
installation paths (e.g., /else/where/usr/local/pgsql/bin). This allows
users to install the package into a location different from the one that
was configured and hard-coded into various scripts, e.g., for creating
binary packages.

DESTDIR is in many cases preferrable over `make install
prefix=/else/where' because

a) `prefix' affects the path that is hard-coded into the files, which can
lead to a `make install prefix=xxx' (as done by the regression test
driver) corrupting the files in the source tree with wrong paths.

b) it doesn't work at all if a directory was overridden to not depend on
`prefix', e.g., --sysconfdir=/etc.

(Updating the regression test driver to use DESTDIR is a separate
undertaking.)

The latter updated accordingly. Also add `dist' and `distcheck' targets

marginally builddir aware and fix the usual set of things.

Add rule to automatically remake config.h dependent on config.h.in and
config.status. (Adopted from Autoconf manual and about every other

of dependencies throughout everything.

Handle include file installation in src/include/Makefile

genbki.sh improvements: Don't substitute anything by config.status,
instead pass in AWK and CPP through environment. Change calling
convention to support named output files, so we get to see error
messages on stderr.

Rename bootstrap template files and install them into PREFIX/share.
Update initdb to that effect and other readability improvements
