I'm not sure what problem you're trying to solve with an approach like
this, but a quick test confirms that a query such as:

select response
from paths
where '/users/1234' similar to path

would actually work. Of course, it will require setting up a custom
sql condition, but that's not really a huge deal. As for the previous
reply, a sequential table scan on 10k records isn't a big deal for
PostgreSQL on any modern machine, in fact I rarely even think about
indices until tables are at least approaching 10k records and usually
well beyond.
