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