In the contrib/intarray benchmarking script bench.pl, the -e option to print
the plan via EXPLAIN is using the DBI do() method which discards output
resulting in nothing being printed. Judging by the usage help (“show explain”)
I assume the intention is to print the plan to STDOUT when invoked (which is
exactly what I wanted in this case, thus bumping into this) but at least on
recent DBI/DBD::Pg versions the do() method is not returning the rows.
Attached patch use the selectall_arrayref() method instead and output the plan
when -e is invoked.
