Incompatibility with timescale

PGSync version: 2.1.1
Postgres version: 13
Elasticsearch version: 7
Redis version: 6.2
Python version: 3.7

Problem Description:

It seems pgsync does not work with TimescaleDB, throwing the following error during bootstrap:

This was briefly discussed at https://github.com/toluaina/pgsync/issues/43, but the discussion went another direction.

I also found a similar issue on alembic, also coming from the same underlying problem in SQLAlchemy: https://github.com/sqlalchemy/alembic/issues/733

Is there a workaround for this, or is it not possible to use PGSync with TimescaleDB at the moment?
