should we enable log_checkpoints out of the box?

Hi,

It seems the checkpoint stats, that are emitted to server logs when
the GUC log_checkpoints is enabled, are so important that a postgres
database provider would ever want to disable the GUC. Right now, the
GUC is disabled by default and a postgres database provider needs to
enable it explicitly. How about we
enable it out of the box? One disadvantage is that it may fill up the
server logs if the checkpoints are so frequent. However the
checkpoints stats are captured even when the GUC is disabled [1].

Thoughts?

MemSet(&CheckpointStats, 0, sizeof(CheckpointStats));
