array. This allows processing of conninfo strings to be made thread-safe,
at the cost of a small memory leak in applications that use
PQconndefaults() and are not updated to free the returned array via
the new PQconninfoFree() function. But PQconndefaults() is probably not
used very much, so this seems like a good compromise.
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!

platform (psql and libpq):
The file "config.h.win32" in the include\ directory (from my patch from
2000-01-18) is missing from the tree. It needs to be put back :-)
The following patch has to be applied in the interfaces\libpq directory.

thinks the connection is idle, the error message is displayed as if
it were a NOTICE. This seems better than dropping the message on
the floor ... particularly if the message is the backend telling us
why it's about to close the connection. The previous behavior was
Backend message type 0x45 arrived while idle
pqReadData() -- backend closed the channel unexpectedly.
which is not real helpful.

Severity: important
'char' is not a signed type by default on powerpc; therefore a character
can
never be equal to EOF (-1). A patch is attached.

accesses versus sequential accesses, a (very crude) estimate of the
effects of caching on random page accesses, and cost to evaluate WHERE-
clause expressions. Export critical parameters for this model as SET
variables. Also, create SET variables for the planner's enable flags
(enable_seqscan, enable_indexscan, etc) so that these can be controlled
more conveniently than via PGOPTIONS.
Planner now estimates both startup cost (cost before retrieving
first tuple) and total cost of each path, so it can optimize queries
with LIMIT on a reasonable basis by interpolating between these costs.
Same facility is a win for EXISTS(...) subqueries and some other cases.
Redesign pathkey representation to achieve a major speedup in planning
(I saw as much as 5X on a 10-way join); also minor changes in planner
to reduce memory consumption by recycling discarded Path nodes and
not constructing unnecessary lists.
Minor cleanups to display more-plausible costs in some cases in
EXPLAIN output.
Initdb forced by change in interface to index cost estimation
functions.
where else to mail it. I am the maintainer of unixODBC, and we have a
set of code in our project that started life as the Postgres windows
ODBC driver, which has been ported back to unix. Anyway I have just
fixed a memory leak in the driver, and I cant see any mention of the fix
being done in the main Postgres code, so I thougth I would let you know.
Its in the statement.c module, after the COMMIT statement has been
executed in SC_Execute, the code was

it seems more suitable for the naming convention in libpq.
New function PQsetClientEncoding added. It makes possible to change
the client encoding on the fly without setting PGCLIENTENCODING.
Initdb help correction
Changed end/abort to commit/rollback and changed related notices
Commented out way old printing functions in libpq
Fixed a typo in alter table / alter column
compiler warnings caused by lack of extern declarations in extern.h.
I believe the remaining gcc warnings here would go away if the ecpg
grammar could be tweaked so it doesn't use REJECT ...
