## F.11. dblink — connect to other PostgreSQL databases

`dblink` is a module that supports connections to other PostgreSQL databases from within a database session. 

`dblink` can report the following wait events under the wait event type `Extension`. 

**`DblinkConnect`**

 Waiting to establish a connection to a remote server. **`DblinkGetConnect`**

 Waiting to establish a connection to a remote server when it could not be found in the list of already-opened connections. **`DblinkGetResult`**

 Waiting to receive the results of a query from a remote server. See also [Section F.40](postgres-fdw.md), which provides roughly the same functionality using a more modern and standards-compliant infrastructure.
