xfs' slowness is proportional to the *number* rather than the *size* of
the files. In postgres you'll tend to have fewer, larger, files than you
would in (e.g.) a source code repository, so it is generally more
important to have a filesystem that deletes large files quickly than a
filesystem that deletes lots of files quickly. I'd suspect that the same
is true for mythtv.
