H= i, ALL,

On the page https://www.postgresql.o= rg/docs/current/runtime-config-query.html#GUC-SEQ-PAGE-COST
it is only given the default value of this parameter.

No min/max values are provided..

The same can be sad about
https://www.postgresql.org/d= ocs/current/runtime-config-query.html#GUC-RANDOM-PAGE-COST

Costs can=E2=80=99t be negative and no reason= able positive value is going to exceed the data type limit, which is commun= icated via the data type specification.
