Assuming that the changes are reasonably safe, I think you're
right. What parts of the changes would require an initdb, would new
functions need to be added or the index ops need to change or would
it be fixes to the existing functions (if the latter, wouldn't a recompile
and dropping/recreating the indexes be enough?)
