I think what he means is what happens if you change the compression_factor
without rebuilding the database. Will the decompression code be able to
make sense of the compressed data even though it was compressed using a
different factor than the one now selected. My understanding was that
this would work properly, as long as you didn't set it to 0, which would
turn off decompression altogether. I haven't tested this myself, though.
