METHODS
Mojo::Pg::Results inherits all methods from Mojo::Base and implements the following new ones.

arrays
my $collection = $results->arrays;
Fetch all rows from "sth" and return them as a Mojo::Collection object containing array references.
# Process all rows at once
say $results->arrays->reduce(sub { $a + $b->[3] }, 0);
columns
my $columns = $results->columns;
Return column names as an array reference.
# Names of all columns
say for @{$results->columns};
expand
$results = $results->expand;
Decode json

new
my $results = Mojo::Pg::Results->new;
my $results = Mojo::Pg::Results->new(sth => $sth);
my $results = Mojo::Pg::Results->new({sth => $sth});
