You mean four different object types. I'm not totally clear on bison's
scaling behavior relative to the number of productions, but I think
there's no question that this patch will impose a measurable distributed
penalty on every single query issued to Postgres by any application,
whether it's heard of tsearch or not. The percentage overhead would
be a lot lower if the patch were introducing a similar number of entries
into pg_proc.
