ALTER EXTENSION plrust UPDATE error

[iliastsa]

Hello, we recently updated our plrust version from v1.0.0 to latest release. However, I am getting the following when trying to update the extension version to 1.1:

> ALTER EXTENSION plrust UPDATE;
ERROR:  extension "plrust" has no update path from version "1.0" to version "1.1"
SQL state: 22023

Any help/pointers would be appreciated!
