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.
