FYI,
   the  huge memory allocation problem of the PGLZ compressor is   fixed.  It uses a fixed, static history table,
organizedas a   double linked list, now.
 
   No performance loss on small- to medium-sized attributes. But   a win on huge (multi-MB) attributes because  of
much lesser   memory consumption.
