PDO_PGSQL DSN - Connecting to PostgreSQL databases

	The PDO_PGSQL Data Source Name (DSN) is composed of the following elements, delimited by spaces or semicolons:

	      o DSN prefix
		- The DSN prefix is pgsql:.

	      o host - The hostname on which the database server resides.

	      o port - The port on which the database server is running.

	      o dbname - The name of the database.

	      o user  -  The  name of the user for the connection. If you specify the user name in the DSN, PDO ignores the value of the user name
		argument in the PDO constructor.

	      o password - The password of the user for the connection. If you specify the password in the DSN, PDO ignores the value of the pass-
		word argument in the PDO constructor.

       Note

	       The bytea fields are returned as streams.
