I see someone missed an ancient bit of shell-scripting lore:
on some older shells, if your script's argument list is empty,
then "$@" generates an empty-string word rather than no word
at all. You need to write ${1+"$@"} to get the latter behavior.
(Read your shell man page to see exactly how that works,
but it does the Right Thing on every Bourne shell.)
In particular, pg_dumpall fails when invoked without any switches
on HPUX 9.*, because pg_dump gets an empty-string argument that it
thinks is the name of the database to dump. I expect this bug
also affects some other OSes, but couldn't tell you just which ones.
Patch attached.
Making PQrequestCancel safe to call in a signal handler turned out to be
much easier than I feared. So here are the diffs.
Some notes:
* I modified the postmaster's packet "iodone" callback interface to allow
the callback routine to return a continue-or-drop-connection return
code; this was necessary to allow the connection to be closed after
receiving a Cancel, rather than proceeding to launch a new backend...
Being a neatnik, I also made the iodone proc have a typechecked
parameter list.
* I deleted all code I could find that had to do with OOB.
* I made some edits to ensure that all signals mentioned in the code
are referred to symbolically not by numbers ("SIGUSR2" not "2").
I think Bruce may have already done at least some of the same edits;
I hope that merging these patches is not too painful.
I have implemented a framework of encoding translation between the
backend and the frontend. Also I have added a new variable setting
command:
SET CLIENT_ENCODING TO 'encoding';
Other features include:
Latin1 support more 8 bit cleaness
See doc/README.mb for more details. Note that the pacthes are
against May 30 snapshot.

syntax that can be read back in with psql. I did this by adding
a
"-c" switch that controls moving the CONTSTRAINT statements inside
the CREATE TABLE statements and adding () around the CHECK arguments.
Here's diffs against the 6.3.2 version of pg_dump.c.
ccb
psql in Postgres 6.3.2. Both of these problems were complained of
recently in pgsql-questions:
1. In the right circumstances, psql.c will fail to compile due to
trying
to include a nonexistent <history.h>. (Thread "Compile-time
error" around 17 Apr 98.) 2. In other circumstances, psql will
compile but does not provide
command history capability, even though the underlying readline
library supports it. (Various threads, most recently "query
repetition in psql" around 29 Apr.)

1. Rewritten libpq to allow asynchronous clients.
2. Implemented client side of cancel protocol in library,
and patched psql.c to send a cancel request upon SIGINT. The
backend doesn't notice it yet :-(
3. Implemented 'Z' protocol message addition and renaming of
copy in/out start messages. These are implemented conditionally,
ie, the client protocol version is checked; so the code should
still work with 1.0 clients.
4. Revised protocol and libpq sgml documents (don't have an SGML
compiler, though, so there may be some markup glitches here).
What remains to be done:
1. Implement addition of atttypmod field to RowDescriptor messages.
The client-side code is there but ifdef'd out. I have no idea
what to change on the backend side. The field should be sent
only if protocol >= 2.0, of course.
2. Implement backend response to cancel requests received as OOB
messages. (This prolly need not be conditional on protocol
version; just do it if you get SIGURG.)
3. Update libpq.3. (I'm hoping this can be generated mechanically
from libpq.sgml... if not, will do it by hand.) Is there any
other doco to fix?
4. Update non-libpq interfaces as necessary. I patched libpgtcl
so that it would compile, but haven't tested it. Dunno what
needs to be done with the other interfaces.
Have at it!

Attached you'll find a (big) patch that fixes make dep and make
depend in all Makefiles where I found it to be appropriate.
It also removes the dependency in Makefile.global for NAMEDATALEN
and OIDNAMELEN by making backend/catalog/genbki.sh and bin/initdb/initdb.sh
a little smarter.
This no longer requires initdb.sh that is turned into initdb with
a sed script when installing Postgres, hence initdb.sh should be
renamed to initdb (after the patch has been applied :-) )
This patch is against the 6.3 sources, as it took a while to
complete.
Please review and apply,
Cheers,

probleme number 1 :
- configure can find the library readline , but don't
find the header file . so in this case we don't use lib readline
.
probleme number 2 :
- when you have postgres 6.2.1 and readline installed
with the same prefix( and generally all your software ) . you
can compile the version 6.3 . I use this prefix , when configure
ask me for "Additional directories to search for include files"
.
( because there a conflict in the header when you
compile psql.c ) In this case, you must permut the sequence of
directive -I .

yyerror ones from bison. It also includes a few 'enhancements' to
the C programming style (which are, of course, personal).
The other patch removes the compilation of backend/lib/qsort.c, as
qsort() is a standard function in stdlib.h and can be used any
where else (and it is). It was only used in
backend/optimizer/geqo/geqo_pool.c, backend/optimizer/path/predmig.c,
and backend/storage/page/bufpage.c

There's more to come. Please review these patches. I ran the
regression tests and they only failed where this was expected
(random, geo, etc).
Cheers,
Jeroen
seems that my last post didn't make it through. That's good
since the diff itself didn't covered the renaming of
pg_user.h to pg_shadow.h and it's new content.
Here it's again. The complete regression test passwd with
only some float diffs. createuser and destroyuser work.
pg_shadow cannot be read by ordinary user.
Hi -- a couple of small items concerning the January 23rd snapshot:
the inclusion of the Kerberos stuff in one Makefile, a "leading tab"
cleanup in another, and a fix for a typo in the configure script.
This is a patch to fix crashes in psql when executing queries from
an external file. The code also adds error checking to verify that
memory for "query" was allocated. The conditional for the block of
code was changed from "query == NULL" to "query_alloced == false".
The conditional, "query == NULL", was never true. This prevented
the memory being allocated for "query". A few lines later, an attempt
to write to an un-allocated memory area generated a SIGSEGV causing
the frontend to crash.
varchar length.
Cleans up code so attlen is always length.
Removed varchar() hack added earlier.
Will fix bug in selecting varchar() fields, and varchar() can be
variable length.
o A new patch that contains the following changes:
-- The pg_pwd file is now cached in the postmaster's memory.
-- pg_pwd is reloaded when the postmaster detects a flag file creat()'ed
by a backend.
-- qsort() is used to sort loaded password entries, and bsearch() is
is used to find entries in the pg_pwd cache.
-- backends now copy the pg_user relation to pg_pwd.pid, and then
rename the temp file to be pg_pwd.
-- The delimiter for pg_pwd has been changed to a tab character.
src. It is in the function ParseACL. When I find that I
can not allocate enough memory for the ACL structure I
return an NULL instead of doing an exit_nicely(g_conn);

Clean up formatting of code
Integrate new functions into dumpTable
This is not tested yet...have to recompile server due to patches from
Todd...but this compiles cleanly as it stands now
