rather than executing the INTO clause with non-plpgsql semantics
as it was doing for the last few weeks/months. This keeps our options
open for making it do the right plpgsql-ish thing in future without
creating a backwards compatibility problem. There is no loss of
functionality since people can get the same behavior with CREATE TABLE AS.
in pghackers list. Support for oldstyle internal functions is gone
(no longer needed, since conversion is complete) and pg_language entry
'internal' now implies newstyle call convention. pg_language entry
'newC' is gone; both old and newstyle dynamically loaded C functions
are now called language 'C'. A newstyle function must be identified
by an associated info routine. See src/backend/utils/fmgr/README.
maintained for each cache entry. A cache entry will not be freed until
the matching ReleaseSysCache call has been executed. This eliminates
worries about cache entries getting dropped while still in use. See
my posting to pg-hackers of even date for more info.
particular, allow linking with arbitrary commands rather than only $(AR) or
$(LD), and treat C++ without hacks.
Add option to disable shared libraries. This takes the place of the
BSD_SHLIB variable. The regression test driver ignores the plpgsql test
if there are no shared libraries available.
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.)

incarnations (I hope). When an acceptable flex version is not found, print
instructive error messages from both configure and the makefiles, so that
users can continue building anyway.
for example, an SQL function can be used in a functional index. (I make
no promises about speed, but it'll work ;-).) Clean up and simplify
handling of functions returning sets.
right thing with variable-free clauses that contain noncachable functions,
such as 'WHERE random() < 0.5' --- these are evaluated once per
potential output tuple. Expressions that contain only Params are
now candidates to be indexscan quals --- for example, 'var = ($1 + 1)'
can now be indexed. Cope with RelabelType nodes atop potential indexscan
variables --- this oversight prevents 7.0.* from recognizing some
potentially indexscanable situations.
The latter updated accordingly. Also add `dist' and `distcheck' targets
to play with, but caveat packager.
Updated backend/bootstrap and backend/parser makefile to make them
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
package.) On a good day we should now have a complete and accurate set
of dependencies throughout everything.
memory contexts. Currently, only leaks in expressions executed as
quals or projections are handled. Clean up some old dead cruft in
executor while at it --- unused fields in state nodes, that sort of thing.
standard targets and behaviour. Replaced Makefile.in's with
Makefile's and declared the respective variables in Makefile.global.
maintainer-clean target now available at top level, although it does
not work in the backend tree yet.
Cleanup pass over Makefile.shlib, renamed some targets and variables.
The shared library symlink tests are now done by make, not the shell.
ecpg: Remove one warning in sloppy flex output.
PL/Perl and Perl interface: the MakeMaker documentation is confusing,
the realclean target *does* "delete derived files", but it also
uninstalls them. Don't use that.
The submake targets in the various bin directories that update libpq
should `make all', not `make libpq.a'. That is a) unportable, and
b) doesn't build the shared library.
we'll get there one day.
Use `cat' to create aclocal.m4, not `aclocal'. Some people don't
have automake installed.
Only run the autoconf rule in the top-level GNUmakefile if the
invoker specified `make configure', don't run it automatically
because of CVS timestamp skew.
CPP) to create platform independent files. Unfortunately, that means that
every config.status (or configure) run invariably causes a relink of the
postmaster and also that we can't put these files in the distribution
(usefully). So we make it a little smarter: when the output files already
exist and it notices that it would recreate them in identical form, it
doesn't touch them. In order to avoid re-running the make rule all the time
we update a timestamp file instead.
Update release_prep accordingly. Also make Gen_fmgrtab.sh use the awk that
is detected at configure time, not necessarily named `awk' and have it check
for exit statuses a little better.
In other news... Remove USE_LOCALE from the templates, it was set to `no'
everywhere anyway. Also remove YACC and YFLAGS from the templates, configure
is smart enough to find bison or yacc itself. Use AC_PROG_YACC for that
instead of the hand-crafted code. Do not set YFLAGS to `-d'. The make rules
that need this flag should explicitly invoke it. YFLAGS should be a user
variable. Update the makefiles to that effect.
inputs have been converted to newstyle. This should go a long way towards
fixing our portability problems with platforms where char and short
parameters are passed differently from int-width parameters. Still
more to do for the Alpha port however.
key call sites are changed, but most called functions are still oldstyle.
An exception is that the PL managers are updated (so, for example, NULL
handling now behaves as expected in plperl and plpgsql functions).
NOTE initdb is forced due to added column in pg_proc.
mappings. In fact, it had them backward because it was using the 6.5.*
code. Copied them from parser/gram.y, so it is fixed now. Looks like
our first 7.0.1 fix. Oops, seems Tom has beat me to it as I was typing
this.
1) adds NetBSD shared lib support on both ELF and a.out platforms
2) replaces "-L$(LIBPQDIR) -lpq" with "$(LIBPQ)" defined in
Makefile.global. This makes it much easier to build stuff in
the source tree after you've already installed the libraries.
3) adds TEMPLATEDIR in Makefile.global that indicates where the
database templates are stored. This separates the template files
from real libraries that are installed in $(LIBDIR).
4) changes include order of <readline/readline.h> and <readline.h>.
The latest GNU readline installs its headers under a readline
subdirectory.
In addition to applying the patch below the following files need to be copied:
backend/port/dynloader:
bsd.h -> netbsd.h
bsd.c -> netbsd.c
include/port:
bsd.h -> netbsd.h
makefiles:
Makefile.bsd -> Makefile.netbsd
It would be great to see this incorporated into the source tree before
the 7.0 release is cut.
Thanks!

to the typelem or typmod parameters to these functions. In particular,
incorrect code in pg_aggregate.c explains the platform-specific failures
that have been reported in NUMERIC avg().
expressions were written without spaces between operators and operands.
Problem was that something like "if new.f1=new.f2 then" would be translated
to "if $1=$2 then", and the Postgres lexer would tokenize that the wrong
way. Fix is to emit spaces around $paramno constructs to ensure they are
seen as separate tokens.
Make all system indexes unique.
Make all cache loads use system indexes.
Rename *rel to *relid in inheritance tables.
Rename cache names to be clearer.
I have changed a bit the makefiles for the win32 port - the *.def files
(created when building shared libraries) are now clean from
Makefile.shlib.
I have also removed "-g" from CFLAGS in the "cygwin32" template - it can
be
enabled when running configure.

instead of doing a kill(self, SIGQUIT) and expecting the signal handler
to do it. Also, clean up inconsistent definitions of the sigjmp buffer
in the several files that already referenced it.
I have solved some problems with dynamic loading on NT. It is possible
to
run succesfully both trigger and plpgsql regression tests. The patch is
in
the included file "diff".
Dan
but others declare it as extern char *. gcc complains (quite rightly too).
Worked around it by rearranging the order of inclusions so that we don't
have to explicitly declare yytext; this should work with either variant.
src/Makefile.shlib. Updated all the makefiles that try to build shlibs
to include that file instead of having duplicate (and mostly incomplete)
copies of shared-library options. It works on HPUX, a lot better than it
did before in fact, but there's a chance I broke some other platforms.
At least now you only have to fix one place not six...
Get the permissions right, don't overwrite real files with symlinks, etc.
plpgsql and odbc still aren't fully up to speed, but at least they don't crash and burn...
following patches fix the problems (i.e., all regression tests pass)
in what I hope to be a platform-independent fashion. The accomplish
