Previously the logical replication launcher stored the last timestamp when it started the worker, in the local variable "last_start_time", in order to check whether wal_retrive_retry_interval elapsed since the last startup of worker. If it has elapsed, the launcher sees pg_subscription and starts new worker if necessary. This is for limitting the startup of worker to once a wal_retrieve_retry_interval. The bug was that the variable "last_start_time" was defined and always initialized with 0 at the beginning of the launcher's main loop. So even if it's set to the last timestamp in later phase of the loop, it's always reset to 0. Therefore the launcher could not check correctly whether wal_retrieve_retry_interval elapsed since the last startup. This patch moves the variable "last_start_time" outside the main loop so that it will not be reset.
