Description:

The [official
document](https://wiki.postgresql.org/wiki/Tuning_Your_PostgreSQL_Server)
recommends to set **checkpoint_segments** to at least 10, which improves the
performance.
"Unless you're running on a very small configuration, you'll almost
certainly be better setting this to at least 10, which also allows usefully
increasing the completion target."

I wonder if the default need to be changed for performance concern. Thanks.
