The current code uses semaphores, which has the advantage that it works
well even on multi-processor machines, but the disadvantage that it is not
the fastest way possible. Writing a spinlock on Alpha for SMP machines is
very difficult, as you need to deal with memory barriers. A real mess. But
then one of the people at Compaq pointed out to us that there is a
ready-made routine on Alpha. We implemented it with the two patches below.
I ran tests with lots of parallel back-ends and got around a 10% speed
increase. I include the two patches. Perhaps some of the other people
running Tru64 can have a look at these as well.

this is patch v 0.4 to support transactions with BLOBs.
All BLOBs are in one table. You need to make initdb.

tongue about the sloppiness of (a) submitting and (b) committing this
file.

the make program that was used to build itself.  This seems more correct
than guessing around for some gmake.

        It builds and run nicely now

        it seem that the resultmap file have not been updated.

necessary for the postgres/postmaster link, not every link.

after that dynamic loading isn't working and shared memory handling is
broken.

        Attached with this message, there is a Zip file which contain :

        * beos.diff = patch file generated with difforig
        * beos = folder with beos support files which need to be moved in /
src/backend/port
        * expected = foler with three file for message and precision
difference in regression test
        * regression.diff = rule problem (need to kill the backend manualy)
        * dynloader = dynloader files (they are also in the pacth files,
but there is so much modification that I have join full files)

        Everything works except a problem in 'rules' Is there some problems
with rules in the current tree ? It used to works with last week tree.

took some rejiggering of typename and ACL parsing, as well as moving
parse_analyze call out of parser().  Restructure postgres.c processing
so that parse analysis and rewrite are skipped when in abort-transaction
state.  Only COMMIT and ABORT statements will be processed beyond the raw
parser() phase.  This addresses problem of parser failing with database access
errors while in aborted state (see pghackers discussions around 7/28/00).
Also fix some bugs with COMMIT/ABORT statements appearing in the middle of
a single query input string.
Function, operator, and aggregate arguments/results can now use full
TypeName production, in particular foo[] for array types.
DROP OPERATOR and COMMENT ON OPERATOR were broken for unary operators.
Allow CREATE AGGREGATE to accept unquoted numeric constants for initcond.

Indeed it was.

Fix misspelling of disbursion to dispersion.

SQL92 semantics, including support for ALL option.  All three can be used
in subqueries and views.  DISTINCT and ORDER BY work now in views, too.
This rewrite fixes many problems with cross-datatype UNIONs and INSERT/SELECT
where the SELECT yields different datatypes than the INSERT needs.  I did
that by making UNION subqueries and SELECT in INSERT be treated like
subselects-in-FROM, thereby allowing an extra level of targetlist where the
datatype conversions can be inserted safely.
INITDB NEEDED!
