It seems that in the new PL/Perl, the result of the spi_exec_query
function changes in meaning depending on the command. For a SELECT,
the value of
$res->{rows}
is a reference to an array of the result rows.
For a different command
$res->{rows}
is a scalar containing the number of affected rows. I think this is a
poor design. Couldn't we have a different result field that always
contains the number of rows?
