Fix missing space before WHERE in GRAPH_TABLE deparse get_graph_pattern_def() emitted the pattern-level WHERE keyword as "WHERE " with no leading space, so reverse-parsing produced output like "(o IS orders)WHERE (...)". The element-level WHERE deparse in get_path_pattern_expr_def() already prepends a separating space; the pattern-level branch was inconsistent with it. Emit " WHERE " to match.
The output still re-parses to the same tree, so this is cosmetic. For test coverage, add a whole-pattern WHERE clause to the existing customers_us view, which is already reverse-parsed with pg_get_viewdef().
