If build_subscription_ddl_string is "internal" as its comment claims,
why is it declared extern in ruleutils.h? I think it should be a static
function instead. If you want to make it extern, it should live in
src/backend/catalog/pg_subscription.c and its prototype in
src/include/catalog/pg_subscription.h. And if you do move it to
pg_subscription.c (but I don't necessarily agree with that), then you
don't need a third copy of textarray_to_stringlist.
