require "pgsql"

Pg::Conn.open :dbname => "test1", :user => "jdoe" do |conn|
  conn.exec "SELECT * FROM mytable;" do |result|
  result.each { |row|
    l = row.join ", "
    ...
  }
  end
  cmd = <<~ENDSQL
    SELECT * FROM mytable WHERE num=$1::INTEGER;
  ENDSQL
  conn.query cmd, 42 do |row|
    l = row.join ", "
    ...
  end
  ...
end
