DBLINK_DISCONNECT(3)    PostgreSQL 9.5.0 Documentation    DBLINK_DISCONNECT(3)

NAME
       dblink_disconnect - closes a persistent connection to a remote database

SYNOPSIS
       dblink_disconnect() returns text
       dblink_disconnect(text connname) returns text

DESCRIPTION
       dblink_disconnect() closes a connection previously opened by
       dblink_connect(). The form with no arguments closes an unnamed
       connection.

ARGUMENTS
       connname
           The name of a named connection to be closed.

RETURN VALUE
       Returns status, which is always OK (since any error causes the function
       to throw an error instead of returning).

EXAMPLES
           SELECT dblink_disconnect();
            dblink_disconnect
           -------------------
            OK
           (1 row)

           SELECT dblink_disconnect('myconn');
            dblink_disconnect
           -------------------
            OK
           (1 row)
