I agree that allowing just lz4 - is already a huge step ahead.
But I'd suggest supporting zstd as well. Currently we only compress 8Kb chunks and zstd had no runaway to fully unwrap
it'spotential.
In WAL-G we observed ~3x improvement in network utilisation when switched from lz4 to zstd in WAL archive compression.
BTW we could get rid of whole hole-in-a-page thing if we would set lz4 as default. This could simplify FPI code.
Thanks!
