Обсуждение: pgsql: Eliminate replication protocol error related to IDENTIFY_SYSTEM.

Eliminate replication protocol error related to IDENTIFY_SYSTEM.

The requirement that IDENTIFY_SYSTEM be run before START_REPLICATION
was both undocumented and unnecessary. Remove the error and ensure
that ThisTimeLineID is initialized in START_REPLICATION.

Elect not to backport because this requirement was expected behavior
(even if inconsistently enforced), and is not likely to cause any
major problem.
