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.
lock before older waiters, and having readlock people not share
locks if a writer is waiting for a lock, and waiting writers not
getting priority over waiting readers.
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.
The attached patches will allow postgreSQL to compile successfully on SCO
UNIXWARE 2.1.x. The patches fix the following problems:
1. Configure did not properly recognize the UNIXWARE system as needing the
univel port. It used the sys4 port.
2. Configure did not properly process the CC flag in the template file.
3. There was no working test and set locking implementation for the native
UNIXWARE compiler.
4. The test and set locking used for Intel X86 that was selected by defining
NEED_I386_TAS_ASM could fail in a multi-processor environment.
5. The makefiles for libpq and libpgtcl did not make a shared library for
the univel port.
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.

One of the design rules of PostgreSQL is extensibility. And
to follow this rule means (at least for me) that there should
not only be a builtin PL. Instead I would prefer a defined
interface for PL implemetations.
Pass List* of Aggregs into executor, and create needed array there.
No longer need to double-processs Aggregs with second copy in Query.
Fix crash when doing:
select sum(x+1) from test where 1 > 0;
