tables=$(psql ${SRCPG} -AXtwc "SELECT quote_ident(nspname) || '.' || quote_ident(relname) AS name FROM pg_class c JOIN pg_namespace n ON c.relnamespace = n.oid WHERE relkind = 'r' AND nspname !~ '^pg_' AND nspname !~ '^_' AND nspname !~ '^timescaledb' AND nspname !~ '^citus' AND nspname !~ '^columnar' AND nspname NOT IN ('pg_catalog', 'information_schema', 'pg_toast', 'repack', 'monitor');")

, the fully qualified table names should be used in copy-progress. Otherwise, tables not in search_path or tables that share the same relname may not be correctly displayed.
