To ensure that "make installcheck" can be used safely against an existing
installation, we need to be careful about what global object names
(database, role, and tablespace names) we use; otherwise we might
accidentally clobber important objects. There's been a weak consensus that
test databases should have names including "regression", and that test role
names should start with "regress_", but we didn't have any particular rule
about tablespace names; and neither of the other rules was followed with
any consistency either.
This commit moves us a long way towards having a hard-and-fast rule that
regression test databases must have names including "regression", and that
test role and tablespace names must start with "regress_". It's not
completely there because I did not touch some test cases in rolenames.sql
that test creation of special role names like "session_user". That will
require some rethinking of exactly what we want to test, whereas the intent
of this patch is just to hit all the cases in which the needed renamings
are cosmetic.
There is no enforcement mechanism in this patch either, but if we don't
add one we can expect that the tests will soon be violating the convention
again. Again, that's not such a cosmetic change and it will require
discussion. (But I did use a quick-hack enforcement patch to find these
cases.)

This makes the psql() method much more capable: it captures both stdout
and stderr; it now returns the psql exit code rather than stdout; a
timeout can now be specified, as can ON_ERROR_STOP behavior; it gained a
new "on_error_die" (defaulting to off) parameter to raise an exception
if there's any problem. Finally, additional parameters to psql can be
passed if there's need for further tweaking.
For convenience, a new safe_psql() method retains much of the old
behavior of psql(), except that it uses on_error_die on, so that
problems like syntax errors in SQL commands can be detected more easily.
Many existing TAP test files now use safe_psql, which is what is really
wanted. A couple of ->psql() calls are now added in the commit_ts
tests, which verify that the right thing is happening on certain errors.
Some ->command_fails() calls in recovery tests that were verifying that
psql failed also became ->psql() calls now.

This makes the log files easier to follow when investigating a test

The original code was a bit clunky; make it more amenable for further
reuse by creating a new Perl package PostgresNode, which is an
object-oriented representation of a single server, with some support
routines such as init, start, stop, psql. This serves as a better basis
on which to build further test code, and enables writing tests that use
more than one server without too much complication.
This commit modifies a lot of the existing test files, mostly to remove
explicit calls to system commands (pg_ctl) replacing them with method
calls of a PostgresNode object. The result is quite a bit more
straightforward.
Also move some initialization code to BEGIN and INIT blocks instead of
having it straight in as top-level code.
This commit also introduces package RecursiveCopy so that we can copy
whole directories without having to depend on packages that may not be
present on vanilla Perl 5.8 installations.
I also ran perltidy on the modified files, which changes some code sites
that are not otherwise touched by this patch. I tried to avoid this,
but it ended up being more trouble than it's worth.

Some of the TAP tests were supposing that PG programs would accept switches
after non-switch arguments on their command lines. While GNU getopt_long()
does allow that, our own implementation does not, and it's nowhere
suggested in our documentation that such cases should work. Adjust the
tests to use only the documented syntax.
Back-patch to 9.4, since without this the TAP tests fail when run with
src/port's getopt_long() implementation.

They turned out to be too much of a portability headache, because they
need a fairly new version of Test::More to work properly.

When running vacuumdb --analyze-in-stages --all, it needs to run the
first stage across all databases before the second one, instead of
running all stages in a database before processing the next one.
Also respect the --quiet option with --analyze-in-stages.

This includes removing tabs after periods in C comments, which was
applied to back branches, so this change should not effect backpatching.

Add vacuumdb option --analyze-in-stages which runs ANALYZE three times
with different configuration settings, adopting the logic from the
analyze_new_cluster.sh script that pg_upgrade generates. That way,
users of pg_dump/pg_restore can also use that functionality.
Change pg_upgrade to create the script so that it calls vacuumdb instead
of implementing the logic itself.
