The vertical tightness settings collapse vertical whitespace between
opening and closing brackets (parentheses, square brakets and braces).
This can make data structures in particular harder to read, and is not
very consistent with our style in non-Perl code. This patch restricts
that setting to parentheses only, and reformats all the perl code
accordingly. Not applying this to parentheses has some unfortunate
effects, so the consensus is to keep the setting for parentheses and not
for the others.
The diff for this patch does highlight some places where structures
should have trailing commas. They can be added manually, as there is no
automatic tool to do so.

In tests that check whether a connection fails, also check the error
message. That makes sure that the connection was rejected for the right
reason.
This discovered that two tests had their connection failing for the
wrong reason. One test failed because pg_hba.conf was not set up to
allow that user, one test failed because the client key file did not
have the right permissions. Fix those tests and add a new one that is
really supposed to check the file permission issue.

Instead of using the psql/libpq connection string as the displayed test
name and relying on "notes" and source code comments to explain the
tests, give the tests self-explanatory names, like we do elsewhere.

Connection strings can have items with spaces in them, wrapped in
quotes. The tests however ran a SELECT '$connstr' upon connection which
broke on the embedded quotes. Use dollar quotes on the connstr to
protect against this. This was hit during the development of the macOS
Secure Transport patch, but is independent of it.

This is the basic feature set using OpenSSL to support the feature. In
order to allow the frontend and the backend to fetch the sent and
expected TLS Finished messages, a PG-like API is added to be able to
make the interface pluggable for other SSL implementations.
This commit also adds a infrastructure to facilitate the addition of
future channel binding types as well as libpq parameters to control the
SASL mechanism names and channel binding names. Those will be added by
upcoming commits.
Some tests are added to the SSL test suite to test SCRAM authentication
with channel binding.

Move the sub-routines wrappers to check if a connection to a server is
fine or not into the test main module. This is useful for other tests
willing to check connectivity into a server.

Reduce noise from TAP tests by changing 'diag' to 'note', so output only
goes to the test's log file not stdout, unless in verbose mode. This
also removes the junk on screen when running the TAP tests in parallel.

It is no longer necessary to restart the server to enable, disable,
or reconfigure SSL. Instead, we just create a new SSL_CTX struct
(by re-reading all relevant files) whenever we get SIGHUP. Testing
shows that this is fast enough that it shouldn't be a problem.
In conjunction with that, downgrade the logic that complains about
pg_hba.conf "hostssl" lines when SSL isn't active: now that's just
a warning condition not an error.
An issue that still needs to be addressed is what shall we do with
passphrase-protected server keys? As this stands, the server would
demand the passphrase again on every SIGHUP, which is certainly
impractical. But the case was only barely supported before, so that
does not seem a sufficient reason to hold up committing this patch.

There were several issues with the old coding:
1. There was a race condition, if two threads opened a connection at the
same time. We used a mutex around SSL_CTX_* calls, but that was not
enough, e.g. if one thread SSL_CTX_load_verify_locations() with one
path, and another thread set it with a different path, before the first
thread got to establish the connection.
2. Opening two different connections, with different sslrootcert settings,
seemed to fail outright with "SSL error: block type is not 01". Not sure
why.
3. We created the SSL object, before calling SSL_CTX_load_verify_locations
and SSL_CTX_use_certificate_chain_file on the SSL context. That was
wrong, because the options set on the SSL context are propagated to the
SSL object, when the SSL object is created. If they are set after the
SSL object has already been created, they won't take effect until the
next connection. (This is bug #14329)
At least some of these could've been fixed while still using a shared
context, but it would've been more complicated and error-prone. To keep
things simple, let's just use a separate SSL context for each connection,
and accept the overhead.

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.

Create a log file for each test run. Stdout and stderr of the test script,
as well as any subprocesses run as part of the test, are redirected to
the log file. This makes it a lot easier to debug test failures. Also print
the test output (ok 12 - ... messages) to the log file, and the command
line of any external programs executed with the system_or_bail and run_log
functions. This makes it a lot easier to debug failing tests.
Modify some of the pg_ctl and other command invocations to not use 'silent'
or 'quiet' options, and don't redirect output to /dev/null, so that you get
all the information in the log instead.
In the passing, construct some command lines in a way that works if $tempdir
contains quote-characters. I haven't systematically gone through all of
them or tested that, so I don't know if this is enough to make that work.
pg_rewind tests had a custom mechanism for creating a similar log file. Use
the new generic facility instead.

It's not run by the global "check" or "installcheck" targets, because the
temporary installation it creates accepts TCP connections from any user
the same host, which is insecure.
