As a user, I feel I would look for such information in appendix like "A 
Database limits" in Oracle's Database Reference manual:

https://docs.oracle.com/en/database/oracle/oracle-database/18/refrn/database-limits.html#GUID-ED26F826-DB40-433F-9C2C-8C63A46A3BFE

As a somewhat related topic, PostgreSQL doesn't mention the maximum values for 
numeric parameters.  I was asked several times the questions like "what's the 
maximum value for max_connections?" and "how much memory can I use for 
work_mem?"  I don't feel a strong need to specify those values, but I wonder if 
we should do something.
