# class Object

### Constants

PGError

  Backward-compatible aliase

PGconn

  The PostgreSQL connection class. The interface for this class is based on libpq, the C application programmer's interface to PostgreSQL. Some familiarity with libpq is recommended, but not necessary.

  For example, to send query to the database on the localhost:

      require 'pg'
      conn = PG::Connection.open(:dbname => 'test')
      res = conn.exec_params('SELECT $1 AS a, $2 AS b, $3 AS c', [1, 2, nil])
      # Equivalent to:
      #  res  = conn.exec('SELECT 1 AS a, 2 AS b, NULL AS c')

  See the PG::Result class for information on working with the results of a query.
