## dblink_disconnect

    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.
