+1 for adding Zstd everywhere. Quite similar patches are already a part of "libpq compression" and "zstd for pg_dump"
commitfestentries, so pushing this will simplify those entries IMV.
Also I like the idea of defaulting FPI compression to lz4 and adding Zstd as wal_compression option.
I don't think Zstd is obvious choice for default FPI compression: there are HW setups when disks are almost as fast as
RAM.In this case lz4 can improve performance, while Zstd might make things slower.
Thanks!
