pglogical trouble on BDR cluster

Hi. I currently have a two-server BDR replication setup. Apart from the two
master nodes, I have another two servers which I want to have read only
replication for some tables only.

I first had to deal with some trouble regarding CREATE EXTENSION being
replicated by BDR, and that causing the schema creation for the extension to
be run on both servers, thus locking the entire cluster. I solved that by
creating the schema, tables and function manually, and replacing the
extension SQL file with an empty one.

Now, after joining the subscriber to the provider, I keep getting the
following log in the provider:

< 2017-07-02 13:30:38.776 -05 >ERROR: missing required parameter
"startup_params_format"

< 2017-07-02 13:30:38.776 -05 >CONTEXT: slot
"pgl_ocs_test_dayana_jimena_dayana", output plugin "pglogical_output", in
the startup callback

And in the subscriber:

"pglogical apply 192166:2763588059"

< 2017-07-02 13:29:39.835 CEST >LOG: unregistering background worker
"pglogical apply 192166:2763588059"

I've searched all around the source code & document5ation, but I see no way
to set that parameter, so I'm stucked here. Any help would be appreciated.
