Matches Oracle Flashback Data Archive (FDA) system-generated auxiliary table names, which begin with the SYS_FBA_ prefix, continue with uppercase letters/underscores (e.g., SYS_FBA_HIST, SYS_FBA_DDL_COLMAP), and end with an underscore plus a 5-6 digit object ID. Useful for DBAs auditing schemas, filtering data dictionary exports, or identifying hidden FDA tracking tables. The gm flags apply it globally across multiple lines.
