Change pgbench to use the table names pgbench_accounts, pgbench_branches,
pgbench_history, and pgbench_tellers, rather than just accounts, branches,
history, and tellers.  This is to prevent accidental conflicts with real
application tables, as has been reported to happen at least once.  Also
remove the automatic "SET search_path = public" that it did at startup,

Heikki Linnakangas [Thu, 7 May 2009 11:25:25 +0000 (11:25 +0000)]
Request XLOG switch before writing checkpoint in pg_start_backup(). Otherwise
you can end up with an unrecoverable backup if you start a new base backup
right after finishing archive recovery. In that scenario, the redo pointer of
the checkpoint that pg_start_backup() writes points to the XLOG segment where
the timeline-changing end-of-archive-recovery checkpoint is. The beginning
of that segment contains pages with the old timeline ID, and we don't accept
that in recovery unless we find a history file covering the old timeline ID.
If you omit pg_xlog from the base backup and clear the archive directory
before starting the backup, there will be no such history file available.

The bug is present in all versions since PITR was introduced in 8.0, but I'm
back-patching only back to 8.2. Earlier versions didn't have XLOG switch
records, making this fix unfeasible. Given the lack of reports until now,

response to the issue that we might load third-party code that doesn't know it

backend shutdown, if possible.  (Of course, if the reason for the exit() call

Tom Lane [Tue, 5 May 2009 19:59:00 +0000 (19:59 +0000)]
Install a "dead man switch" to allow the postmaster to detect cases where
a backend has done exit(0) or exit(1) without having disengaged itself
from shared memory.  We are at risk for this whenever third-party code is
loaded into a backend, since such code might not know it's supposed to go
through proc_exit() instead.  Also, it is reported that under Windows
there are ways to externally kill a process that cause the status code
returned to the postmaster to be indistinguishable from a voluntary exit
(thank you, Microsoft).  If this does happen then the system is probably
hosed --- for instance, the dead session might still be holding locks.
So the best recovery method is to treat this like a backend crash.

The dead man switch is armed for a particular child process when it
acquires a regular PGPROC, and disarmed when the PGPROC is released;
these should be the first and last touches of shared memory resources
in a backend, or close enough anyway.  This choice means there is no
coverage for auxiliary processes, but I doubt we need that, since they
shouldn't be executing any user-provided code anyway.

This patch also improves the management of the EXEC_BACKEND
ShmemBackendArray array a bit, by reducing search costs.

Although this problem is of long standing, the lack of field complaints
seems to mean it's not critical enough to risk back-patching; at least
not till we get some more testing of this mechanism.

Insert CHECK_FOR_INTERRUPTS() calls into btree and hash index scans at the

reasonable response time to a query cancel request during an unsuccessful
index scan, as seen in recent gripe from Marc Cousin.  It's a bit trickier
than it might seem at first glance, because CHECK_FOR_INTERRUPTS() is a no-op
if executed while holding a buffer lock.  So we have to do it just at the
point where we've dropped one page lock and not yet acquired the next.

Remove CHECK_FOR_INTERRUPTS calls at the top level of btgetbitmap and
hashgetbitmap, since they're pointless given the added checks.

I think that GIST is okay already --- at least, there's a CHECK_FOR_INTERRUPTS
at a plausible-looking place in gistnext().  I don't claim to know GIN well
enough to try to poke it for this, if indeed it has a problem at all.

Tom Lane [Sat, 25 Apr 2009 16:44:56 +0000 (16:44 +0000)]
Fix the handling of sub-SELECTs appearing in the arguments of an outer-level
aggregate function.  By definition, such a sub-SELECT cannot reference any
variables of query levels between itself and the aggregate's semantic level
(else the aggregate would've been assigned to that lower level instead).
So the correct, most efficient implementation is to treat the sub-SELECT as
being a sub-select of that outer query level, not the level the aggregate
syntactically appears in.  Not doing so also confuses the heck out of our
parameter-passing logic, as illustrated in bug report from Daniel Grace.

Fortunately, we were already copying the whole Aggref expression up to the
outer query level, so all that's needed is to delay SS_process_sublinks
processing of the sub-SELECT until control returns to the outer level.

This has been broken since we introduced spec-compliant treatment of
outer aggregates in 7.4; so patch all the way back.

Revise plpgsql's scanner to process comments and string literals in a way
more nearly matching the core SQL scanner.  The user-visible effects are:

* Block comments (slash-star comments) now nest, as per SQL spec.

* In standard_conforming_strings mode, backslash as the last character of a
  non-E string literal is now correctly taken as an ordinary character;
  formerly it was misinterpreted as escaping the ending quote.  (Since the
  string also had to pass through the core scanner, this invariably led
  to syntax errors.)

* Formerly, backslashes in the format string of RAISE were always treated as
  quoting the next character, regardless of mode.  Now, they are ordinary
  characters with standard_conforming_strings on, while with it off, they
  introduce the same set of escapes as in the core SQL scanner.  Also,
  escape_string_warning is now effective for RAISE format strings.  These
  changes make RAISE format strings work just like any other string literal.

This is implemented by copying and pasting a lot of logic from the core
scanner.  It would be a good idea to look into getting rid of plpgsql's
scanner entirely in favor of using the core scanner.  However, that involves
more change than I can justify making during beta --- in particular, the core
scanner would have to become re-entrant.

In passing, remove the kluge that made the plpgsql scanner emit T_FUNCTION or
T_TRIGGER as a made-up first token.  That presumably had some value once upon
a time, but now it's just useless complication for both the scanner and the
grammar.
