pgsql: Fix checkpoint after fast promotion.

Fix checkpoint after fast promotion.

The intention was to request a regular online checkpoint immediately after
end of recovery, when performing "fast promotion". However, because the
checkpoint was requested before other backends were allowed to write WAL,
the checkpointer process performed a restartpoint rather than a checkpoint.

Delay the RequestCheckPoint call until after recovery has truly ended, so
that you get a real checkpoint.
