Hi,

I'm trying to execute a BEFORE UPDATE trigger for my logical replication 
subscription with Postgresql 10.1 but the apply worker crashes with:

ERROR:  attempted to lock invisible tuple


The trigger creation:

CREATE TRIGGER customers_anonymize_before_update BEFORE UPDATE ON 
customers FOR EACH ROW EXECUTE PROCEDURE customers_anonymize();

The "BEFORE INSERT" trigger seems to work fine.

I found this Issue on 2ndQuadrant: 
https://github.com/2ndQuadrant/pglogical/issues/97

Is this on the radar? Is it already fixed?

Thanks
BR
Thomas
