quietlytreated as tables (which, of course, they are.) In v14, sequences were not treated as tables, nor checked at
all. In this new patch, sequences are quietly treated the same way as tables. By "quietly", I mean there are no
command-lineswitches to specifically filter them in or out separately from filtering ordinary tables.

materializedviews matching a table name pattern would be checked, so this new behavior is not entirely out of line with
theold behavior.
