If the number of nodes in a way didn't change you could optimize by just

I was thinking you could take the maximum of every node's distance
from the other way. It should yield the same metric as ST_Buffer
would.
I tried that by using ST_MaxDistance but it fails for some cases where
the maximum distance is actually quite large even though the linestrings
are near each other.
