pg_fact_loader does not explicitly depend on pglogical_ticker (it can be used with or without), however, some of the test suite does depend on it. I'm not sure exactly how that needs to be configured but wanted to point it out.
Both of these build fine with pg_buildext/debuild. You will see the debian directory which should meet all requirements.
Please let us know if there's anything else you need, and I appreciate your help with these!
