This is just one of my results:
668     ./filelists.sqlite.bz2
536     ./filelists.xml.gz
128     ./other.sqlite.bz2
92      ./other.xml.gz
472     ./primary.sqlite.bz2
212     ./primary.xml.gz
4       ./repomd.xml

for filelists the sqlite is smaller by almost half.

You can see primary is_NOT 30% larger but more like 120% larger.  Although
filelists is only around 25% larger. So...?

If the patch is done right it can give each individual user their desired
results. It would be easy to add a switch to the command like the opensuse
patch does. ie

createrepo --lzma\xz\bz2\gz

and leave the default as gz for xml files and bz2 for sqlite files. That way
nothing changes for the normal default usage, but if one would like to
enhance their compression of the xml or sqlite files, that would be their
choice to add the extra switch. I don't understand why that gets confused
with trying to masquerade and being compatible?
