ERROR: relation "state_forward_extremities" does not exist

Hi,

When I run the script on matrix-synapse v0.99.5.2 I get the following error: ERROR: relation "state_forward_extremities" does not exist. See the full log bellow:

~/synapse_scripts$ psql matrix < synapse_janitor.sql

Thanks in advance for your help.
