View definition: SELECT n.nspname AS schemaname, c.relname AS tablename, pg_get_userbyid(c.relowner) AS tableowner, c.relhasindex AS hasindexes, c.relhasrules AS hasrules, (c.reltriggers > 0) AS hastriggers FROM (pg_class c LEFT JOIN pg_namespace n ON ((n.oid = c.relnamespace))) WHERE ((c.relkind = 'r'::"char") OR (c.relkind = 's'::"char"));

Given that 'S' => Sequence and 's' => special shouldn't the last condition in the WHERE clause be:

c.relkind = 'S'::"char"

instead of

c.relkind = 's'::"char"
