Please note that the patch does not apply.  FWIW, I still don't think
that this is a good idea to have that.  I don't recall seeing much on
this list that users would like to have such a level of tuning for
pglz, while lz4 only offers the option to reduce the compression rate
while being already very cheap in CPU so the impact is limited.  On
top of that, this adds a new attribute to pg_attribute with much more
complexity into ALTER TABLE code paths in tablecmds.c..
