Another documentation issue - Mailing list pgsql-general

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

However, this page
https://www.postgresql.org/docs/current/runtime-config-resource.html#GUC-EFFECTIVE-IO-CONCURRENCY
describes both default and mn/max, however t s says:

[quote]
The default is 1 on supported systems, otherwise 0
[/quote]]

No explanation of what is "supported system" is given...

And the same can be said about
https://www.postgresql.org/docs/current/runtime-config-resource.html#GUC-MAINTENANCE-IO-CONCURRENCY.

Thank you
