Fixes for problems created when processing regular expressions that
generate very large automata. An enormous number of thanks to Will
Drewry <wad@google.com>, Tavis Ormandy <taviso@google.com>, and Tom
Lane <tgl@sss.pgh.pa.us> from the Postgresql crowd for their help in
tracking these problems down. [Bug 1810264]
