The logic to start WAL receiver early should not be coupled with recovery_min_apply_delay GUC. WAL receiver's delayed
startaffects replication in general, even when the GUC is not set.
A better fix would be to start WAL receiver in the main replay loop, as soon as consistent state has been reached.
As noted during previous reviews, scanning all WAL just to determine streaming start point seems slow. A faster
solutionseems desirable.
