to DAY precision or coarser; leave the timezone alone when precision is
HOUR or less. This avoids surprises for inputs near a DST transition
time, as per example from Matthew Gabeler-Lee. (The only reason we
recalculate at all is so that outputs that are supposed to represent
days will come out as local midnight, and that's not relevant for sub-day
precision.)
use it, as per my proposal of yesterday. This gives us a means of
determining the zone offset to impute to an unlabeled timestamp that
is both efficient and reliable, unlike all our previous tries involving
mktime() and localtime(). The behavior for invalid or ambiguous times
at a DST transition is fixed to be really and truly "assume standard
time", fixing a bug that has come and gone repeatedly but was back
again in 7.4. (There is some ongoing discussion about whether we should
raise an error instead, but for the moment I'll make it do what it was
previously intended to do.)
interesting for MS to catch all those dumps...
Anyway. Oops. Seems I ran my regression tests with the old psql, and
just managed to update the backend, when I tested that patch. Turns out
there are codepaths where we'd access the Critical Section before it was
initialized. Attached patch breaks the initializeation off to a separate
part and adds that one to a much earlier position in the program.

of psql; this should make it easier to diagnose client-side problems,
such as library version mismatch. Also, consistently use -X option
to avoid problems from weird .psqlrc settings.

of HeapTupleSatisfiesItself() to trigger a hint-bit update on the tuple:
if the row was updated or deleted by a subtransaction of my own transaction
that was later rolled back. This cannot occur in pre-8.0 of course, so
the hint-bit patch applied a couple weeks ago is OK for existing releases.
But for 8.0 it seems we had better fix things so that RI_FKey_check can
pass the correct buffer number to HeapTupleSatisfiesItself. Accordingly,
add fields to the TriggerData struct to carry the buffer ID(s) for the
old and new tuple(s). There are other possible solutions but this one
seems cleanest; it will allow other AFTER-trigger functions to safely
do tqual.c calls if they want to. Put new fields at end of struct so
that there is no API breakage.
We can't regurgitate the unconverted string as I first thought, because
the elog.c mechanisms will assume the error message data is in the server
encoding and attempt a reverse conversion. Eventually it might be worth
providing a short-circuit path to support this, but for now the simplest
solution is to abandon trying to report back the line contents after a
conversion failure. Per bug report from Sil Lee, 27-Oct-2004.
'recycled log files' and 'removed log files' messages from DEBUG1 to
DEBUG2, replacing them with a count of files added/removed/recycled in
the checkpoint end message, as per suggestion from Simon Riggs.

The code was trying to find a connection by name when it already had an
unnamed connection and did not have a name to search with.

files and directories. This ensures that the bgwriter will close any open
file references it is holding for files therein, which is needed for the
rmdir() to succeed. Andrew Dunstan and Tom Lane.
try to display it as a reference to the underlying column instead. This
is a legitimate substitution (it wouldn't be for a named join) and it
fixes some cases where the display would otherwise be ambiguous. Per
example from Sim Zacks.
in all cases when keep_buf = true. This allows ANALYZE's inner loop to
use heap_release_fetch, which saves multiple buffer lookups for the same
page and avoids overestimation of cost by the vacuum cost mechanism.
