Hi, ALL,
On the page https://www.postgresql.org/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/docs/current/runtime-config- query.html#GUC-RANDOM-PAGE- COST
Costs can’t be negative and no reasonable positive value is going to exceed the data type limit, which is communicated via the data type specification.
