Done:
o -ALTER TABLE ADD COLUMN does not honor DEFAULT and non-CHECK CONSTRAINT
o -ALTER TABLE ADD COLUMN column DEFAULT should fill existing
rows with DEFAULT value
o -Allow ALTER TABLE to modify column lengths and change to binary
compatible types
Remove:
o Allow columns to be reordered using ALTER ... POSITION i col1 [,col2];
have SELECT * and INSERT honor such ordering

ALTER TABLE rewrite. New cool stuff:
* ALTER ... ADD COLUMN with defaults and NOT NULL constraints works per SQL
spec. A default is implemented by rewriting the table with the new value
stored in each row.
* ALTER COLUMN TYPE. You can change a column's datatype to anything you
want, so long as you can specify how to convert the old value. Rewrites
the table. (Possible future improvement: optimize no-op conversions such
as varchar(N) to varchar(N+1).)
* Multiple ALTER actions in a single ALTER TABLE command. You can perform
any number of column additions, type changes, and constraint additions with
only one pass over the table contents.
Basic documentation provided in ALTER TABLE ref page, but some more docs
work is needed.

More cleanup of thread tests.
Translation updates
Unconditionally define:
-D_REENTRANT -D_THREAD_SAFE -D_POSIX_PTHREAD_SEMANTICS
for all ports. It can't hurt if they are not supported, but it makes
our job easier for porting.
Should fix Darwin compile and other platforms without mucking with the
thread detection code.
Clean tools/thread on make clean/distclean.
Exit with non-zero error on thread test failures.
More thread error improvments.
More thread error message improvments.
More thread error improvements.
Improve thread error message.
Improve error message for platform thread failure.
Tiny assorted fixes: correct a typo in a comment in vacuumlazy.c, remove
some unused #include directives from bufmgr.c, and clarify comments in
bufmgr.h and buf.h
More thread cleanups.
Add mention to check config.log if thread test failure.
Fix typo on thread lib name.
Make thread flags CFLAGS, not CPPFLAGS.
No need to use our standard libs for the thread test --- they might not
be compiled yet.
Remove the last traces of Joe Hellerstein's "xfunc" optimization. Patch
from Alvaro Herrera. Also, removed lispsort.c, since it is no longer
used.
Fix typo in libpq docs.
Document that PQoidValue(), PQcmdTuples(), and PQoidStatus() now work

appropriate prepared statement.

Ensure getaddrinfo_all returns null result on failure.
Check for gmake, then make, when doing thread test.
Add mention to run thread test program if user is experiencing problems
with threaded applications.
Hook thread_test program run at the end of configure run.
Add test for cross-compiles that they have to run the thread_test
program on the target machine.
Report error if thread-test is run without having threading enabled in
configure.
Improve thread test program. Test only functions that need testing.
Add ceiling() as an alias for ceil(), and power() as an alias for pow().
Regression tests and documentation have both been updated.
SQL2003 requires that both ceiling() and ceil() be present, so I have
documented both spellings. SQL2003 doesn't mention pow() as far as I
can see, so I decided to replace pow() with power() in the documentation:
there is little reason to encourage the continued usage of a function
that isn't compliant with the standard, given a standard-compliant
alternative.
RELEASE NOTES: should state that pow() is considered deprecated
(although I don't see the need to ever remove it.)
Add new auto-detection of thread flags.
Allow additional thread flags to be added via port templates.
Change thread flag names to PTHREAD_CFLAGS and PTHREAD_LIBS to match new
configure script.
Fixed memory misusage in variable handling.

contains OIDs. Also, minor documentation improvements to the
psql reference page.

Update EXECUTE docs to mention tag matches prepared statement.
Update log_statement to more clearly state it doesn't filter based on
the statement type of the prepared statement.
Per discussion earlier today, here is a fix that lets ereport() on win32
report socket errors.

Attached is are a few small fixes for dbmirror.
1. Fixed bug where sequences were being mirrored incorrectly if they
exceeded 127
2. Fixed a bug in the perl script with mirroring sequences(John
Burtenshaw sent an email to patches describing the bug in March but I
htink he forgot to attach his patch)
3. The dates/times in the transaction files will always use 2 digits.

This patch makes the EXECUTE command's completion tag return the
completion tag of the actual statement executed. This allows the
correct update count to be returned for UPDATE/INSERT/DELETE

Tweak indexscan and seqscan code to arrange that steps from one page to
the next are handled by ReleaseAndReadBuffer rather than separate
ReleaseBuffer and ReadBuffer calls. This cuts the number of acquisitions
of the BufMgrLock by a factor of 2 (possibly more, if an indexscan happens
to pull successive rows from the same heap page). Unfortunately this
doesn't seem enough to get us out of the recently discussed context-switch
storm problem, but it's surely worth doing anyway.
Tom Lane [2004年4月21日 18:06:30 +0000 (18:06 +0000)]
Another round of code cleanup on bufmgr. Use BM_VALID flag to keep track
of whether we have successfully read data into a buffer; this makes the
error behavior a bit more transparent (IMHO anyway), and also makes it
work correctly for local buffers which don't use Start/TerminateBufferIO.
Collapse three separate functions for writing a shared buffer into one.
This overlaps a bit with cleanups that Neil proposed awhile back, but
seems not to have committed yet.
