This commit, in completion of 157f873, forces a ROLLBACK for
--single-transaction only when ON_ERROR_STOP is used when one of the
steps defined by -f/-c fails. Hence, COMMIT is always used when
ON_ERROR_STOP is not set, ignoring the status code of the last action
taken in the set of switches specified by -c/-f (previously ROLLBACK
would have been issued even without ON_ERROR_STOP if the last step
failed, while COMMIT was issued if a step in-between failed as long as
the last step succeeded, leading to more inconsistency).
While on it, this adds much more test coverage in this area when not
using ON_ERROR_STOP with multiple switch patterns involving -c and -f
for query files, single queries and slash commands.
The behavior of ON_ERROR_STOP is arguably a bug, but there was no much
support for a backpatch to force a ROLLBACK on a step failure, so this
change is done only on HEAD for now.
Per discussion with Tom Lane and Kyotaro Horiguchi.

Some locales use a comma as decimal separator (like Czech or French),
and psql's 001_basic.pl for \timing was not able to handle that
properly. This fixes the matching regexes to be able to handle both
comma and dot as possible decimal separators, as per a suggestion from
Andrew Dunstan.
psql tests were the only place with such a portability issue
(check-world passed here with a forced LANG/LANGUAGE). These tests are
new as of c0280bc, so there is no need for a backpatch.

psql --single-transaction is able to handle multiple -c and -f switches
in a single transaction since d5563d7d, but this had the surprising
behavior of forcing a transaction COMMIT even if psql failed with an
error in the client (for example incorrect path given to \copy), which
would generate an error, but still commit any changes that were already
applied in the backend. This commit makes the behavior more consistent,
by enforcing a transaction ROLLBACK if any commands fail, both
client-side and backend-side, so as no changes are applied if one error
happens in any of them.
Some tests are added on HEAD to provide some coverage about all that.
Backend-side errors are unreliable as IPC::Run can complain on SIGPIPE
if psql quits before reading a query result, but that should work
properly in the case where any errors come from psql itself, which is
what the original report is about.

Backpatch-through: 10
The changes to show all query results (7844c9918) broke \timing output
in case of an error; it didn't update the timing result and showed
0.000 ms.
Fix by updating the timing result also in the error case. Also, for
robustness, update the timing result any time a result is obtained,
not only for the last, so a sensible value is always available.

Get rid of the separate "FATAL" log level, as it was applied
so inconsistently as to be meaningless. This mostly involves
s/pg_log_fatal/pg_log_error/g.
Create a macro pg_fatal() to handle the common use-case of
pg_log_error() immediately followed by exit(1). Various
modules had already invented either this or equivalent macros;
standardize on pg_fatal() and apply it where possible.
Invent the ability to add "detail" and "hint" messages to a
frontend message, much as we have long had in the backend.
Except where rewording was needed to convert existing coding
to detail/hint style, I have (mostly) resisted the temptation
to change existing message wording.
Patch by me. Design and patch reviewed at various stages by
Robert Haas, Kyotaro Horiguchi, Peter Eisentraut and
Daniel Gustafsson.

Previously, psql printed only the last result if a command string
returned multiple result sets. Now it prints all of them. The
previous behavior can be obtained by setting the psql variable
SHOW_ALL_RESULTS to off.
This is a significantly enhanced version of
3a5130672296ed4e682403a77a9a3ad3d21cef75 (that was later reverted).
There is also much more test coverage for various psql features now.

Rather than doing manual book keeping to plan the number of tests to run
in each TAP suite, conclude each run with done_testing() summing up the
the number of tests that ran. This removes the need for maintaning and
updating the plan count at the expense of an accurate count of remaining
during the test suite runtime.
This patch has been discussed a number of times, often in the context of
other patches which updates tests, so a larger number of discussions can
be found in the archives.

The five modules in our TAP test framework all had names in the top
level namespace. This is unwise because, even though we're not
exporting them to CPAN, the names can leak, for example if they are
exported by the RPM build process. We therefore move the modules to the
PostgreSQL::Test namespace. In the process PostgresNode is renamed to
Cluster, and TestLib is renamed to Utils. PostgresVersion becomes simply
PostgreSQL::Version, to avoid possible confusion about what it's the
version of.

The tests added by c0280bc and d9ddc50 in 001_basic.pl have introduced
commands calling directly psql, making them sensitive to the
environment. One issue was that those commands forgot -X to not use a
local .psqlrc, causing all those tests to fail if psql cannot properly
parse this file.
TAP tests should be designed so as they run in an isolated fashion,
without any dependency on the environment where they are run. As
PostgresNode::psql gives already all the facilities those new tests
need, switch to that instead of calling plain psql commands where
interactions with a backend are needed. The test is slightly refactored
to be able to check after the expected patterns of stdout and stderr,
keeping the same amount of coverage as previously.
