vulnerability. This fix completely removes the ability (hack) of being able
to bind a list of values in an in clause. It was demonstrated that by allowing
that functionality you open up the possibility for certain types of
sql injection attacks. The previous fix attempts all focused on preventing
the insertion of additional sql statements (the semi-colon problem:
xxx; any new sql statement here). But that still left the ability to
change the where clause on the current statement or perform a subselect
which can circumvent applicaiton security logic and/or allow you to call
any stored function.

psql4win32.patch - changes in the psql source code
psql-ref.patch - changes in the documentation psql-ref.sgml
(for new builtin variable WIN32_CONSOLE)
To apply them use "patch -p 1" in the root directory of the
postgres source directory.
These patches fix the following problems of psql on Win32
(all changes only have effect #ifdef WIN32):
a) Problem: Static library libpq.a did not work
Solution: Added WSAStartup() in fe-connect.c
b) Problem: Secret Password was echoed by psql
Solution: Password echoing disabled in sprompt.c
c) Problem: 8bit characters were displayed/interpreted wrong in psql
This is due to the fact that the Win32 "console" uses a
different encoding than the rest of the Windows system
Solution: Introduced a new psql variable WIN32_CONSOLE
When set with "\set WIN32_console", the function OemToChar()
is applied after reading input and CharToOem() before

spelled out by Magnus Hagander <mha@sollentuna.net> on 2000-08-23 in email

Attached is a new patch, including documentation.
To sum up, there's a new client parameter "sslmode" and environment
variable "PGSSLMODE", with these options:
sslmode description
------- -----------
disable Unencrypted non-SSL only
allow Negotiate, prefer non-SSL
prefer Negotiate, prefer SSL (default)
require Require SSL
The only change to the server is a new pg_hba.conf line type,
"hostnossl", for specifying connections that are not allowed to use SSL
(for example, to prevent servers on a local network from accidentally
using SSL and wasting cycles). Thus the 3 pg_hba.conf line types are:
pg_hba.conf line types
----------------------
host applies to either SSL or regular connections
hostssl applies only to SSL connections
hostnossl applies only to regular connections
These client and server options, the postgresql.conf ssl = false option,
and finally the possibility of compiling with no SSL support at all,
make quite a range of combinations to test. I threw together a test
script to try many of them out. It's in a separate tarball with its
config files, a patch to psql so it'll announce SSL connections even in
absence of a tty, and the test output. The test is especially informative
when run on the same tty the postmaster was started on, so the FATAL:
errors during negotiation are interleaved with the psql client output.

_quote() function fails due to integer overflow if input d is larger
than max integer.
In the case where the column type is "BIGINT", the input d may very well
be larger than max integer while its type, t, is labeled 'int'.
The conversion on line 19, return "%d" % int(d), will fail due to
"OverflowError: long int too large to convert to int".
Please describe a way to repeat the problem. Please try to provide a
concise reproducible example, if at all possible:

I attach a patch that replaces the function with one used to perform the same
task in pyPgSQL (a Python interface to PostgreSQL). This code was written by
Billy Allie, author of pyPgSQL. I've changed a few variable names to match
those in the original code and removed a bit of Pythonness.
Billy has kindly looked at the code and points out that it is slightly
stricter than the original implementation and if it encounters an invalid
bytea such as '\12C' it drops the unescape '\' and outputs '12C'.
The code is licensed by the author under a BSD license.
I've performed limited testing of the function by putting JPEGs into
PostgreSQL, extracting them using them using the new function and diffing
against the original files.
The new function is significantly faster on my machine with the JPEGs being
decoded in less than a second. I attach a modified libpq example program that
I used for my testing.

Restrictions on expressions are the same as for predicates (only immutable

inlining SQL functions, because the inlining transformation is applied to

This was required for server versions < 7.3 when a user did not supply
constraint names. Every constraint was named "<unnamed>"
. 7.3 has enforced unique constraint names per table so unnamed foreign
keys will have different names "$1", "$2" and so on. I've used logic
along the lines of the following to preserve the unique names in the
original scheme, but allow people who go to the trouble of naming their
constraints to see them:
if (triggerargs.startsWith("<unnamed>")) {
fkname = [the whole ugly trigger args name originally used];
} else {
fkname = [the actual fk name];

believe I didn't notice this before -- once 64k was sent to/from the
server the client would crash. Basicly, in 7.3 the server SSL code set
the initial state to "about to renegotiate" without actually starting

handle the SSL_ERROR_WANT_(READ|WRITE) error. This is fixed in the

first, that I missed when checking over 7.3.1, was that the client
method was switched to SSLv23 along with the server. The SSLv23 client
method does SSLv2 by default, but can also understand SSLv3. In our
situation the SSLv2 backwords compatibility is really only needed on the
server. This is the first patch.
The last thing is that I found a way for the server to understand SSLv2
HELLO messages (sent by pre-7.3 clients) but then get them to talk
SSLv3. This is the last one.
Nathan Mueller
"SSLv23_method(void), SSLv23_server_method(void), SSLv23_client_method(void)
A TLS/SSL connection established with these methods will understand the SSLv2,
SSLv3, and TLSv1 protocol. A client will send out SSLv2 client hello messages
and will indicate that it also understands SSLv3 and TLSv1. A server will
understand SSLv2, SSLv3, and TLSv1 client hello messages. This is the best
choice when compatibility is a concern."
This will maintain backwards compatibility for those us that don't use
TLS connections ...

=====================
I suggested an improvement of the inserttable in the PyGreSQL interface
already in January, but seemingly it was never implemented. I was told this
is the right place to get patches in for PyGreSQL, so I'm reposting my patch
here.
I consider the inserttable methode essential in populating the database
because of its benefits in performance compared to insert, so I think this
patch is quite essential. The attachment is an improved version of the
corresponding pg_inserttable function in pgmodule.c, which fixes the
following problems:
* The function raised exceptions because PyList_GetItem was used beyond the
size of the list. This was checked by comparing the result with NULL, but
the exception was not cleaned up, which could result in mysterious errors in
the following Python code. Instead of clearing the exception using
PyErr_Clear or something like that, I avoided throwing the exception at all
by at first requesting the size of the list. Using this opportunity, I also
checked the uniformity of the size of the rows passed in the lists/tuples.
The function also accepts (and silently ignores) empty lists and sublists.
* Python "None" values are now accepted and properly converted to PostgreSQL
NULL values
* The function now generates an error message in case of a line buffer
overflow
* It copes with tabulators, newlines and backslashes in strings now
* Rewrote the buffer filling code which should now run faster by avoiding
unnecessary string copy operations forth and back

of passing a formatting string to have a replacement done and output will
be sent to the standard output exactly as it did before. In addition they
can set it to a file object, sys.stderr for example, and the query string
will be printed to it. Thay can also set it to a method (function) and the
query string will be passed to that method giving them the maximum flexibility
to do whatever they want with the query string.
I will be working with the PyGreSQL documentation shortly and at that time
will properly document this feature.

Notes/caveats:
- added regression tests for the new functionality, all
regression tests pass on my machine
- added pg_dump support
- updated PL/PgSQL to support per-statement triggers; didn't
look at the other procedural languages.
- there's (even) more code duplication in trigger.c than there
was previously. Any suggestions on how to refactor the
ExecXXXTriggers() functions to reuse more code would be
welcome -- I took a brief look at it, but couldn't see an
easy way to do it (there are several subtly-different
versions of the code in question)
- updated the documentation. I also took the liberty of
removing a big chunk of duplicated syntax documentation in
the Programmer's Guide on triggers, and moving that
information to the CREATE TRIGGER reference page.
- I also included some spelling fixes and similar small
cleanups I noticed while making the changes. If you'd like
me to split those into a separate patch, let me know.
