The target of sscanf with a %o format had better be of integer width,
but "mode_t" conceivably isn't that. Another compiler warning seen
only on some platforms; this one I think is potentially a real bug
and not just a warning.
Include the lefttype/righttype columns explicitly (instead of assuming
the reader can deduce them from the operator or function description),
and move the operator or function description to the end of the string,
to make it clearer that it's a referenced object and not the amop or
amproc item itself. Per extensive discussion of Andreas Karlsson's
original patch.

This reverts commit 740e54ca84, which seems
to have tickled an optimization bug in gcc 4.5.x, as reported upstream at
https://bugzilla.redhat.com/show_bug.cgi?id=671899
Since this patch had no purpose beyond code beautification, it's not
worth expending a lot of effort to look for another workaround.
This tool makes it possible to do the pg_start_backup/
copy files/pg_stop_backup step in a single command.
There are still some steps to be done before this is a
complete backup solution, such as the ability to stream
the required WAL logs, but it's still usable, and
could do with some buildfarm coverage.
In passing, make the checkpoint request optionally
fast instead of hardcoding it.

As in commit fb4c5d2798 on 2011-01-21,
this avoids spurious debug messages and allows idempotent changes at
any time. Along the way, make assign_XactIsoLevel allow idempotent
changes even when not within a subtransaction, to be consistent with
the new coding of assign_transaction_read_only and because there's
no compelling reason to do otherwise.
Kevin Grittner, with some adjustments.
It's not clear to me what should happen to the other plpython_unicode
variant expected files, but this patch gets things passing on my own
machines and at least some of the buildfarm.
If wal_buffers is initially set to -1 (which is now the default), it's
replaced by 1/32nd of shared_buffers, with a minimum of 8 (the old default)
and a maximum of the XLOG segment size. The allowed range for manual
settings is still from 4 up to whatever will fit in shared memory.
Greg Smith, with implementation correction by me.
Not sure why I'm seeing this on Fedora 14 and not earlier versions.
Seems like a regression that gcc no longer knows that DIE() doesn't return.
Still, adding a dummy return is harmless enough.
It appears that gcc 4.5 can issue such warnings for whole structs, not
just scalar variables as in the past. Refactor some pg_dump code slightly
so that the OutputContext local variables are always initialized, even
if they won't be used. It's cheap enough to not be worth worrying about.
Global error handling led to confusion and was hard to manage. With
this change, errors from PostgreSQL are immediately reported to Python
as exceptions. This requires setting a Python exception after
reporting the caught PostgreSQL error as a warning, because PLy_elog
destroys the Python exception state.
Ideally, all places where PostgreSQL errors need to be reported back
to Python should be wrapped in subtransactions, to make going back to
Python from a longjmp safe. This will be handled in a separate patch.

Reduce #includes to minimum actually needed; in particular include
postgres_fe.h not postgres.h, so as to stop build failures on some
platforms.
Use get_progname() instead of hardwired program name; improve error
checking for command line syntax; bring error messages into line with
style guidelines; include strerror result in die() cases.
The previous coding treated anything that wasn't an autovacuum launcher
as a normal backend, which is wrong now that we also have WAL senders.
Fujii Masao, reviewed by Robert Haas, Alvaro Herrera, Tom Lane,
and Bernd Helmle.
The new coding avoids a spurious debug message when a transaction
that has changed the isolation level has been rolled back. It also
allows the property to be freely changed to the current value within
a subtransaction.
Kevin Grittner, with one small change by me.
Un-break Windows build (I hope) by making the HAVE_FSYNC_WRITETHROUGH
code match the backend. Fix incorrect program help message. static-ize
all functions.
Actually rename the program, rather than just claiming we did. Hook it
into the build system. Get rid of useless dependency on libpq. Clean up
#include list and messy whitespace.
The way the exception types where added to the module was wrong for
Python 3. Exception classes were not actually available from plpy.
Fix that by factoring out code that is responsible for defining new
Python exceptions and make it work with Python 3. New regression test
makes sure the plpy module has the expected contents.
Jan Urbanśki, slightly revised by me
Failure to do so can lead to constraint violations. This was broken by
commit 1ddc2703a9 on 2010-02-07, so
back-patch to 9.0.
Noah Misch. Regression test by me.
Pay attention to the attisdropped field and skip over TupleDesc fields
that have it set. Not a real problem until we get table returning
functions, but it's the right thing to do anyway.
Jan Urbański
If the function using yield to return rows fails halfway, the iterator
stays open and subsequent calls to the function will resume reading
from it. The fix is to unref the iterator and set it to NULL if there
has been an error.
Jan Urbański
We can get the length of a compressed or out-of-line datum without actually
detoasting it. If the lengths of two strings are unequal, we can then
conclude they are unequal without detoasting. That saves considerable work
in an admittedly less-common case, without costing anything much when the
optimization doesn't apply.
