Please allow this syntax: \[$string, @bind_args] in the table parameter of select

This script doesn't show any bound values in the result. But inserting values like this script, inside the ON of the JOIN is a common scenario, so i think this is needed.

use SQL::Abstract::Pg;
use Data::Dumper;

my $abstract = SQL::Abstract::Pg->new;

my $user_id = 10;
my ($sql, @bind) = $abstract->select(
    \[ 't1 JOIN t2 ON (t1.id = t2.p_id AND t2.user = ?)', $user_id ],
    undef,
);

print Dumper({
    sql  => $sql,
    bind => \@bind,
});

Start by tracing SQL::Abstract::Pg's select handling for the table parameter, using the issue's Perl example as the reproduction case. Run the script and inspect its SQL and bind output; done means the JOIN syntax is accepted and the placeholder's value appears in the returned bind list.
