f85f43dfb5 Backend support for autocommit removed, per recent discussions. The
only remnant of this failed experiment is that the server will take
SET AUTOCOMMIT TO ON.  Still TODO: provide some client-side autocommit
logic in libpq.

d9b679c13a In RowDescription messages, report columns of domain datatypes as having
the type OID and typmod of the underlying base type.  Per discussions
a few weeks ago with Andreas Pflug and others.  Note that this behavioral
change affects both old- and new-protocol clients.

1c9ac7dfd0 Change pg_amop's index on (amopclaid,amopopr) to index (amopopr,amopclaid).
This makes no difference for existing uses, but allows SelectSortFunction()
and pred_test_simple_clause() to use indexscans instead of seqscans to
locate entries for a particular operator in pg_amop.  Better yet, they can
use the SearchSysCacheList() API to cache the search results.

30f609484d Add binary I/O routines for a bunch more datatypes. Still a few to go,
but that was enough tedium for one day.  Along the way, move the few
support routines for types xid and cid into a more logical place.

b02832719c Avoid unnecessary copying of parameter values in BIND. This allows
efficient insertion of large bytea values through the BIND interface.

d97c9b3662 Apply fixes for problems with dropped columns whose types have also been
dropped.  The simplest fix for INSERT/UPDATE cases turns out to be for
preptlist.c to insert NULLs of a known-good type (I used INT4) rather
than making them match the deleted column's type.  Since the representation
of NULL is actually datatype-independent, this should work fine.
I also re-reverted the patch to disable the use_physical_tlist optimization
in the presence of dropped columns.  It still doesn't look worth the
trouble to be smarter, if there are no other bugs to fix.
Added a regression test to catch future problems in this area.

6f261461c1 Revert previous change --- turns out the underlying problem affects
more cases than I thought, so ExecTypeFromTL() will have to be fixed
anyway.

8f2e53bc10 Disable the recently-added use_physical_tlist optimization in cases
where the table contains dropped columns.  If the columns are dropped,
then their types may be gone as well, which causes ExecTypeFromTL() to
fail if the dropped columns appear in a plan node's tlist.  This could
be worked around but I don't think the optimization is valuable enough
to be worth the trouble.

a4e775a263 Make use of new error context stack mechanism to allow random errors
detected during buffer dump to be labeled with the buffer location.
For example, if a page LSN is clobbered, we now produce something like
ERROR:  XLogFlush: request 2C000000/8468EC8 is not satisfied --- flushed only
to 0/8468EF0
CONTEXT:  writing block 0 of relation 428946/566240
whereas before there was no convenient way to find out which page had
been trashed.

ecc8c3652e In child-crashed log messages, identify a checkpoint process as such
instead of calling it a 'server process'.

8d86a96068 Adjust CreateCheckpoint so that buffer dumping activities and cleanup of
dead xlog segments are not considered part of a critical section.  It is
not necessary to force a database-wide panic if we get a failure in these
operations.  Per recent trouble reports.

075a0078df I think we're done with protocol instability, so mark server and libpq

c0a8c3ac13 Update 3.0 protocol support to match recent agreements about how to
handle multiple 'formats' for data I/O.  Restructure CommandDest and
DestReceiver stuff one more time (it's finally starting to look a bit
clean though).  Code now matches latest 3.0 protocol document as far
as message formats go --- but there is no support for binary I/O yet.

137b123fc7 Fixed bug with Warnings. Warnings are not added to the Statement instead of
the connection when appropriate.
This checkin also adds the type map for jdbc3, however currently it is
identical to the jdbc2 mapping.

755d191700 Add display of eventual result RowDescription (if any) to the output
of Describe on a prepared statement.  This was in the original 3.0
protocol proposal, but I took it out for reasons that seemed good at
the time.  Put it back per yesterday's pghackers discussion.

8f6a6b7e9a Ensure that an Execute operation can't send tuples in cases where
Describe would claim that no tuples will be returned.  Only affects
SELECTs added to non-SELECT base queries by rewrite rules.  If you
want to see the output of such a select, you gotta use 'simple Query'
protocol.

79913910d4 Restructure command destination handling so that we pass around
DestReceiver pointers instead of just CommandDest values.  The DestReceiver
is made at the point where the destination is selected, rather than
deep inside the executor.  This cleans up the original kluge implementation
of tstoreReceiver.c, and makes it easy to support retrieving results
from utility statements inside portals.  Thus, you can now do fun things
like Bind and Execute a FETCH or EXPLAIN command, and it'll all work
as expected (e.g., you can Describe the portal, or use Execute's count
parameter to suspend the output partway through).  Implementation involves
stuffing the utility command's output into a Tuplestore, which would be
kind of annoying for huge output sets, but should be quite acceptable
for typical uses of utility commands.
