number of active subtransaction XIDs in each backend's PGPROC entry,
and use this to avoid expensive probes into pg_subtrans during
TransactionIdIsInProgress.  Extend EOXactCallback API to allow add-on
modules to get control at subxact start/end.  (This is deliberately
not compatible with the former API, since any uses of that API probably
need manual review anyway.)  Add basic reference documentation for
SAVEPOINT and related commands.  Minor other cleanups to check off some
of the open issues for subtransactions.

more nearly Oracle-equivalent.  Allow matching by category as well as
specific error code.  Document the set of available condition names
(or more accurately, synchronize it with the existing documentation).  In
passing, update errcodes.sgml to include codes added during 7.5 development.

Create a shared function to convert a SPI error code into a string
(replacing near-duplicate code in several PLs), and use it anywhere
that a SPI function call error is reported.

machines, break tie scores by preferring shorter zone names over longer;
for names of equal length, prefer the alphabetically first name.  This
yields for example 'EST5EDT' not 'America/New_York' for US eastern time.
On Windows, abandon the whole concept of inspecting the detailed behavior
of the system TZ library, because it doesn't bear inspection :-(.  Instead
use a hardwired mapping table to select our zone name based on the
result of strftime %Z output.  Windows code from Magnus Hagander.

PostgresMain.  Per Magnus Hagander.

There are still some things that need refinement; in particular I fear
that the recognized set of error condition names probably has little in
common with what Oracle recognizes.  But it's a start.

OK, having no M$ diff, I attach files src\interfaces\libpq\bcc32.mak and

possible to trap an error inside a function rather than letting it
propagate out to PostgresMain.  You still have to use AbortCurrentTransaction
to clean up, but at least the error handling itself will cooperate.

dates.  Per Magnus Hagander.

some massaging by Peter Eisentraut.  This is basically a simple
generalization of the existing contrib makefiles.

followed by seeing EOF from client.  If we want a safe session-kill
capability we will need to write one, not break our error handling
mechanism.

password/group files.  Also allow read-only subtransactions of a read-write
parent, but not vice versa.  These are the reasonably noncontroversial
parts of Alvaro's recent mop-up patch, plus further work on large objects
to minimize use of the TopTransactionResourceOwner.
