Well, pg_lzcompress is in the backend for more than 6 years now, strange 
the objections arise now. However, a replacement for it might be a good 
idea, since apparently the fastest gzip algorithm is 3x faster for 10% 
better compression. TOAST write performance would probably profit 
significantly from a better algorithm.

I wonder what other use-cases exist for server side copy filters beyond 
compression.
