Maximum time between automatic WAL checkpoints, in seconds. Increasing this parameter can increase the amount of time needed for crash recovery.

Increasing checkpoint_timeout to a larger value, such as 15 minutes, can reduce the I/O load on your system, especially when using large values for shared_buffers.

The downside of making these adjustments to the checkpoint parameters is that your system uses a modest amount of additional disk space and takes longer to recover in the event of a crash. However, for most users, this is worth it for a significant performance improvement.
