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.
target files in implicit rule chains. That might have been a cool idea
but it seems to be too buggy to work, as it caused spurious recompiles in
several places.
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.
add --without-tk option to disable Tk. We don't need the AC_PATH_XTRA
test because tkConfig.sh already contains all the information about how to
compile and link with X. Also make sure that libpq is up to date for
libpgtcl. Remove executable bits from pgaccess.sh, but add it to pgaccess.
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.)

7.0.2 release. Sorry, if that's fixed ages ago - I don't track
development versions of PostgreSQL.
Patch is just a little bit tested (some valid functions created and
successfully run as well as some erroneous ones created and emitted proper
error messages when used).
My platform is FreeBSD 5.0-CURRENT (with perl 5.6.0 provided in the
base system).

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.
in a non-safe interpreter, so with full OS access! Language is
restricted to be used by DB superusers.
Added "argisnull n" and "return_null" commands to gain full control
over NULL values from new FMGR capabilities.

NOTE: this implementation of tcl_avg() fails with 'divide by zero'
for zero input rows. It ought to return NULL, but pltcl does not
currently provide a way to do that, so I'm leaving the problem unsolved
for now.
There's now only one transition value and transition function.
NULL handling in aggregates is a lot cleaner. Also, use Numeric
accumulators instead of integer accumulators for sum/avg on integer
datatypes --- this avoids overflow at the cost of being a little slower.
Implement VARIANCE() and STDDEV() aggregates in the standard backend.
Also, enable new LIKE selectivity estimators by default. Unrelated
change, but as long as I had to force initdb anyway...
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.
Don't use DISABLE_COMPLEX_MACRO on Solaris. Don't define the
replacement function in the header file. Use -KPIC, not -K PIC.
Use CC to link C++ libraries, not ld/ar.
Eliminate file not found warnings in tcl build code.
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.

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.
