Merge branch '169-original-params' into 'master'

fix: extend original params to synchronize on restore – take the following settings from pg_controldata's output:
- max_connections
- max_prepared_transactions
- max_locks_per_transaction
- max_worker_processes
- track_commit_timestamp

This is needed to start up the cluster properly.

Closes #169
