Doc: be more precise about conflicts between relation names.

tglsfdc · tglsfdc · commit af8c580e5cf3 · 2021-11-02T12:12:02.000-04:00
Use verbiage like "The name of the table must be distinct from the name of any other relation (table, sequence, index, view, materialized view, or foreign table) in the same schema." in the reference pages for all those object types. The main change here is to mention materialized views explicitly; although a couple of these pages failed to say anything at all about name conflicts. Per suggestion from Daniel Westermann.
