some platforms --- and I also see that it is documented as not thread-
safe on HPUX and possibly other platforms. No good reason not to just
use IPPROTO_TCP constant from <netinet/in.h> instead.
really ought to fix relcache entry construction so that it does not
do so much with CurrentMemoryContext = CacheCxt. As is, relatively
harmless leaks in either sequential or index scanning translate to
permanent leaks if they occur when called from relcache build.
For the moment, however, the path of least resistance is to repair
all such leaks...
Hiroshi. ReleaseRelationBuffers now removes rel's buffers from pool,
instead of merely marking them nondirty. The old code would leave valid
buffers for a deleted relation, which didn't cause any known problems
but can't possibly be a good idea. There were several places which called
ReleaseRelationBuffers *and* FlushRelationBuffers, which is now
unnecessary; but there were others that did not. FlushRelationBuffers
no longer emits a warning notice if it finds dirty buffers to flush,
because with the current bufmgr behavior that's not an unexpected
condition. Also, FlushRelationBuffers will flush out all dirty buffers
for the relation regardless of block number. This ensures that
pg_upgrade's expectations are met about tuple on-row status bits being
up-to-date on disk. Lastly, tweak BufTableDelete() to clear the
buffer's tag so that no one can mistake it for being a still-valid
buffer for the page it once held. Formerly, the buffer would not be
found by buffer hashtable searches after BufTableDelete(), but it would
still be thought to belong to its old relation by the routines that
sequentially scan the shared-buffer array. Again I know of no bugs
caused by that, but it still can't be a good idea.
RowExclusive (my fault). Also, install a check to prevent people
from trying COPY BINARY to stdout/from stdin. No way that will
work unless we redesign the frontend COPY protocol ... which is
not worth the trouble in the near future ...
is in <string> and not in <string.h> on QNX4/egcs-2.91.60.
Probably this can be changed for all platforms. The test in line 1705 uses
<string> as well. Because I am not sure, I havn't this included into the
patch.
doc/Makefile has to be sligthly modified as it has been done for
src/backend/Makefile due to a QNX4 problem (patch attached)
Furthermore src/test/regress/run_check.sh needs to be patched as it has been
done for regress.sh (patch attached). Please note that in the patch the
postmaster is started always with the -i option.
run_check.sh reports the test "limit" as failed, but in reallity it is OK.
regress.sh reports it as OK.

IRIX systems using the native compilers. A summary is:
- Various files use "//" as a comment delimiter in c files.
- Problems caused by assuming "char" is signed.
cash.in: building -signed the rules regression test fails as described
in FAQ_QNX4. If CHAR_MAX is "255U" then ((signed char)CHAR_MAX) is -1.
postmaster.c: random number regression test failed without this change.
- Some generic build issues and warning message cleanup.

There were a bunch of places that weren't paying attention to configure's
result anyway (including configure itself!?); clean them up too.
I'm including a diff of
postgresql-7.0/src/interfaces/jdbc/org/postgresql/jdbc2/ResultSet.java.
I've clearly marked all the fixes I did. Would *someone* who has access
to the cvs please put this in?

days. It seems to be a FAQ, and I think I know why. When creating a 'c'
language function, CREATE FUNCTION is fed the shared object filename,
and seems to succeed. Only when trying to use the function is an error
thrown, by which time the coder thinks something's wrong with executing
the code, not with loading it.
I think I once saw it proposed to load shared objects at function creation
time, but that idea was shot down on the grounds of resident memory bloat,
ISTR. Here's a patch for a compromise: all it does is stat() the file,
just like the loader code does, so that the errors caused by non existent
files, and no directory 'x' permissions (the most common ones, it seems),
get caught while the developer is still thinking about code loading. It
doesn't catch all errors (like the code not being readable by the postgres
user) but seems to catch the most common, without actually opening the file.
What do you think?

indexes, apparently, nor on functional indexes with more than one input
column (force of natts = 1 was in the wrong branch of IF statement).
Coredumped if source relation contained any uncommitted tuples, due to
failure to test for success return from heap_fetch. Fetched tuple
was passed directly to heap_insert, which clobbers the TID and commit
status in the tuple header it's given, which meant that the source
relation's tuples all got trashed as the copy proceeded. Abort partway
through, and you're left with a lot of missing tuples.
I wonder what else is lurking here ...

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.
