Are any of the usual extensions present in that directory, or is it
just passwordcheck that's missing?

The most obvious bet is that you installed a postgresql-contrib
package that is not really compatible with the server package
you're using and it put all the extension files somewhere else
than where the server expects to find them. Try checking the
file listing for the postgresql-contrib package you used.
