FWIW, this is decided as being a standard rule for any modules/script
added in the main tree.

Why not. I am no perlist but those prove to be helpful, however those
Postgres modules are not dedicated to a large audience, so we could
live without for now.

Thanks for your enthusiasm. Now, to do an auto-critic of my patch:
+ if ($params{allows_streaming})
+ {
+ print $conf "wal_level = hot_standby\n";
+ print $conf "max_wal_senders = 5\n";
+ print $conf "wal_keep_segments = 20\n";
+ print $conf "max_wal_size = 128MB\n";
+ print $conf "shared_buffers = 1MB\n";
+ print $conf "wal_log_hints = on\n";
+ print $conf "hot_standby = on\n";
+ }
This could have more thoughts, particularly for wal_log_hints which is
not used all the time, I think that we'd actually want to complete
that with an optional hash of parameter/values that get appended at
the end of the configuration file, then pass wal_log_hints in the
tests where it is needed. The default set of parameter is maybe fine
if done this way, still wal_keep_segments could be removed.

Two typos in two lines.
