Implement support for PostgreSQL 12 "standby.signal". (#51)

* Implement support for PostgreSQL 12 "standby.signal". In Postgres 12 the setup to start as a standby has changed. The standby configuration parameters go in the main postgresql.conf file, and the decision to start in standby mode depends on the existence of a new file, named "standby.signal". Adapting the code to this new system requires some refactoring.
