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

With a recent commit truncate is transaction safe in 7.4.

As far as I figured from the source code this function only deals with
cleaning up locale names and nothing else. Since all the locale names
are in plain ASCII I think it will be safe to use ASCII-only lower-case
conversion.

localbuf.c must be able to do blind writes.

Avoid pulling up sublinks from a subselect's targetlist. Works around
problems that occur if sublink is referenced via a join alias variable.
Perhaps this can be improved later, but a simple and safe fix is needed
for 7.3.1.

It looks like the problem was introduced when the "SET autocommit" and
"SET search_path" commands were added to the beginning of the script.
The attatched patch should fix the problem. It probably should be
applied against the 7.3 and 7.4 branches.

Clearify variables names so it is clear which variable is the
client-supplied password and which is from pg_shadow.

Allow 'password' encryption even when pg_shadow has MD5 passwords, per
report from Terry Yapt and Hiroshi.
Backpatch to 7.3.

Phase 1 of read-only-plans project: cause executor state nodes to point
to plan nodes, not vice-versa. All executor state nodes now inherit from
struct PlanState. Copying of plan trees has been simplified by not
storing a list of SubPlans in Plan nodes (eliminating duplicate links).
The executor still needs such a list, but it can build it during
ExecutorStart since it has to scan the plan tree anyway.
No initdb forced since no stored-on-disk structures changed, but you
will need a full recompile because of node-numbering changes.
