As someone pointed out, this always dies. In general, you don't
need (or want) to test the results of setting a variable. Also be
aware that in this case you probably want "or" and not "|" - the former
tests the result of "$DB->{AutoCommit} = 0", while the latter actually
tries to set $DB->{AutoCommit} to first "0" and then to the result
of "die". What you want is really

($DB->{AutoCommit} = 0) || die;

which is the same thing, and better written as:

$DB->{AutoCommit} = 0 or die;

Best of all is just to remove the line entirely, as there is no point in
testing the assignment: simply view the contents afterwards:

$DB->{AutoCommit} = 0;
print " |- AutoCommit now: $DB->{AutoCommit}\n";

Also be aware that for DBD::Pg, the following is a known bug
(will be fixed in the upcoming 1.41 release):

> $DB->commit() || die...

In some circumstances commit() returns false when it should return true
(even though it still committed). If you find that happening, simply change
it to $DB->commit(); and trust that the correct thing is indeed happening.
