   <function>pg_close</function> closes the non-persistent
   connection to a PostgreSQL database associated with the given
   <parameter>connection</parameter> instance.

    Using <function>pg_close</function> is not usually necessary, as
    non-persistent open connections are automatically closed at the end
    of the script.

   If there is open <classname>PgSql\Lob</classname> instance on the connection, do not
   close the connection before closing all <classname>PgSql\Lob</classname> instances.
