Acquires a PostgreSQL slave synchronization with a remote master.

Usage

It can be configured globally or per repo as follows:

config :surgex,
  follower_sync_enabled: true,
  follower_sync_timeout: 15_000,
  follower_sync_interval: 1_000

config :my_project, MyProject.MyRepo,
  # ...
  follower_sync_enabled: true,
  follower_sync_timeout: 15_000,
  follower_sync_interval: 1_000

As a convenience versus calling Surgex.DataPipe.FollowerSync.call/2 all the time, it can be used in a repo module as follows:

defmodule MyProject.MyRepo do
  use Surgex.DataPipe.FollowerSync
end

MyProject.MyRepo.ensure_follower_sync(lsn)

Refer to Surgex.DataPipe for a complete data pipe example.
