Answer 1

For parametrized SQL statements, you should use PGconn#exec_params, e.g.

conn = PGconn.new(:dbname => 'test')
conn.exec_params(
    'INSERT INTO comedians (first_name, last_name) VALUES ($1, $2)',
    ['Louis', 'CK'])
conn.close

Look here for a complete list of parameters that can be passed to the PGconn constructor.
