I am not actually that concerned that it takes a long time now that I
know why. I am more concerned that it isn't obvious why it takes so
long. Something like this would be more than sufficient:
elog(NOTICE, "pg_start_backup called, issuing CHECKPOINT");
RequestCheckpoint(CHECKPOINT_FORCE | CHECKPOINT_WAIT);
