# dblink\_disconnect(3)

closes a persistent connection to a remote database

## 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*

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