As for the zstd vs. lz4 - the patch put zstd first mostly because Michael prefers it over lz4. I don't think either of these is superior. AFAIK the algorithms make different trade offs - zstd tends to compress better, but uses (substantially) more CPU. I think it makes sense to default to lz4, it's clearly better than pglz, with low CPU usage.
+1 I think lz4 is the more sensible default due to the low CPU usage. -- Andreas Karlsson Percona
