This my results of compressing pbench data using different compressors:

Configuration	Size (Gb)	Time (sec)
no compression	15.31	92
zlib (default level)	2.37	284
zlib (best speed)	2.43	191
postgres internal lz	3.89	214
lz4	4.12	95
snappy	5.18	99
lzfse	2.80	1099
(apple) 2.80 1099	1.69	125

You see that zstd provides almost 2 times better compression ration and almost at the same speed.

What is "(apple) 2.80 1099"? Was that intended to be zstd?
