I agree having the new functions in the tree is useful. I also tried
running the TAP tests in v2, but 001 and 002 fail to run:

Odd number of elements in hash assignment at [...]/Cluster.pm line 2010.
Can't locate object method "pump_nb" via package
"PostgreSQL::Test::BackgroundPsql" at [...]

It seems to be complaining about

+my $in = '';
+my $out = '';
+my $timeout = IPC::Run::timer($PostgreSQL::Test::Utils::timeout_default);
+my $background_psql = $node->background_psql('postgres', \$in, \$out,
$timeout);

...that call to background_psql doesn't look like other ones that have "key
=> value". Is there something I'm missing?
