This allows logging only some fraction of transactions, greatly reducing
the amount of log generated.

09ac603c36 Work around unportable behavior of malloc(0) and realloc(NULL, 0).
On some platforms these functions return NULL, rather than the more common
practice of returning a pointer to a zero-sized block of memory.  Hack our
various wrapper functions to hide the difference by substituting a size
request of 1.  This is probably not so important for the callers, who
should never touch the block anyway if they asked for size 0 --- but it's
important for the wrapper functions themselves, which mistakenly treated
the NULL result as an out-of-memory failure.  This broke at least pg_dump
for the case of no user-defined aggregates, as per report from
Matthew Carrington.

Back-patch to 9.2 to fix the pg_dump issue.  Given the lack of previous
complaints, it seems likely that there is no live bug in previous releases,
even though some of these functions were in place before that.

a563d94180 Standardize naming of malloc/realloc/strdup wrapper functions.
We had a number of variants on the theme of "malloc or die", with the
majority named like "pg_malloc", but by no means all.  Standardize on the
names pg_malloc, pg_malloc0, pg_realloc, pg_strdup.  Get rid of pg_calloc
entirely in favor of using pg_malloc0.

This is an essentially cosmetic change, so no back-patch.  (I did find
a couple of places where psql and pg_dump were using plain malloc or
strdup instead of the pg_ versions, but they don't look significant
enough to bother back-patching.)

46b2b7e0ff Make pgbench vacuum before building indexes.
This is apparently faster than doing things the other way around when
the scale factor is large.

Along the way, adjust -n to suppress vacuuming during initialization
as well as during test runs.

afe1c51c9d Add pgbench option to add foreign key constraints to the standard scenario.
The option --foreign-keys, used at initialization time, will create foreign
key constraints for the columns that represent references to other tables'
primary keys.  This can help in benchmarking FK performance.

68cbb9f4e7 Modestly improve pgbench's checking for invalid ranges.
The old check against MAX_RANDOM_VALUE is clearly irrelevant since
getrand() no longer calls random().  Instead, check whether min and max
are close enough together to avoid an overflow inside getrand(), as
suggested by Tom Lane.  This is still somewhat silly, because we're
using atoi(), which doesn't check for overflow anyway and (at least on
my system) will cheerfully return 0 when given "4294967296".  But that's
a problem for another commit.

4af43ee3f1 Make pgbench use erand48() rather than random().
glibc renders random() thread-safe by wrapping a futex lock around it;
testing reveals that this limits the performance of pgbench on machines
with many CPU cores.  Rather than switching to random_r(), which is
only available on GNU systems and crashes unless you use undocumented
alchemy to initialize the random state properly, switch to our built-in
implementation of erand48(), which is both thread-safe and concurrent.

Since the list of reasons not to use the operating system's erand48()
is getting rather long, rename ours to pg_erand48() (and similarly
for our implementations of lrand48() and srand48()) and just always
use those.  We were already doing this on Cygwin anyway, and the
glibc implementation is not quite thread-safe, so pgbench wouldn't
be able to use that either.

Per discussion with Tom Lane.

00f76dbffa Get rid of a bunch of dubious error handling code in pgbench by just erroring
out immediately on any out-of-memory condition.  It's rather pointless to
imagine that pgbench will be able to continue usefully after a malloc
failure, and in any case there were a number of unchecked mallocs.

6b45e3b7aa Arrange to generate different random sequences in the different child
processes of a pgbench run, when we are using -j > 1 and are emulating
threads via fork().  Otherwise the children all inherit the same random
sequence state and produce the same random-number sequence.

In the threaded case the different threads will share one RNG state, so
they will produce different subsets of one sequence, which is maybe more
correlated than a purist would like but will not be "the same".  So we
leave that case alone.

First noticed by Takahiro Itagaki, and is also part of the explanation
for the pgbench misbehavior recently reported by Jaime Casanova.

3da0dfb4b1 Multi-threaded version of pgbench contributed by ITAGAKI Takahiro,
reviewed by Greg Smith and Josh Williams.

Following is the proposal from ITAGAKI Takahiro:

Pgbench is a famous tool to measure postgres performance, but nowadays
it does not work well because it cannot use multiple CPUs. On the other
hand, postgres server can use CPUs very well, so the bottle-neck of
workload is *in pgbench*.

Multi-threading would be a solution. The attached patch adds -j
(number of jobs) option to pgbench. If the value N is greater than 1,
pgbench runs with N threads. Connections are equally-divided into
them (ex. -c64 -j4 => 4 threads with 16 connections each). It can
run on POSIX platforms with pthread and on Windows with win32 threads.

Here are results of multi-threaded pgbench runs on Fedora 11 with intel
core i7 (8 logical cores = 4 physical cores * HT). -j8 (8 threads) was
the best and the tps is 4.5 times of -j1, that is a traditional result.

$ pgbench -i -s10
$ pgbench -n -S -c64 -j1   =>  tps = 11600.158593
$ pgbench -n -S -c64 -j2   =>  tps = 17947.100954
$ pgbench -n -S -c64 -j4   =>  tps = 26571.124001
$ pgbench -n -S -c64 -j8   =>  tps = 52725.470403
$ pgbench -n -S -c64 -j16  =>  tps = 38976.675319
$ pgbench -n -S -c64 -j32  =>  tps = 28998.499601
$ pgbench -n -S -c64 -j64  =>  tps = 26701.877815

Is it acceptable to use pthread in contrib module?
If ok, I will add the patch to the next commitfest.

48caf91b66 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,
as this seems to restrict testing flexibility without actually buying much.

- Use DROP IF EXISTS to suppress errors for initial loadings.
- Use a combination of TRUNCATE and COPY to reduce WAL on creating
  the accounts table.

Also, there are some cosmetic changes.

- Change the output of -v option from "starting full vacuum..."
  to "starting vacuum accounts..." in reflection of the fact.
- Shape duplicated error checks into executeStatement().

436a2956d8 Re-run pgindent, fixing a problem where comment lines after a blank
comment line where output as too long, and update typedefs for /lib
directory.  Also fix case where identifiers were used as variable names
in the backend, but as typedefs in ecpg (favor the backend for
indenting).

Backpatch to 8.1.X.

d156e1f850 (Apologies for fat-fingering cvs commit command...) Should have read:
Remove unportable use of tfind/tsearch in favor of bsearch.  Fix up
random number generator to use random() not rand() and to actually honor
its min/max arguments properly.  That wasn't so important before, but
with exposure of capability to ask for general ranges, it will be.

0b36cb83dc PGXS should be set with := not =, as specified in the documentation,
to avoid useless multiple executions of pg_config.
