checkpoint_timout with no WAL activity

[Tom DalPozzo <t.dalpozzo@xxxxxxxxx>]

Hi,

I have:

checkpoint_timeout = 2min

wal_level = archive

archive_mode=on

archive_timeout = 30

With NO dbase activity, I see the WAL being modified every 2min (and, consequently, one WAL file archived every 2min too ).

Is it right? I read: "If no WAL has been written since the previous checkpoint, new checkpoints will be skipped even if checkpoint_timeout has passed."
