PDO_PGSQL-DSN(3) 1 PDO_PGSQL-DSN(3) 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.
