The "Default TOAST compression change to lz4" part is incorrect.
34dfca293432 has switched default_toast_compression to lz4 by default
if we compile by lz4. What has been reverted is 4f0b3afab4da, which
forced --with-lz4 across the buildfarm. So we still have a softer
patch in, and using --with-lz4 will enforce a new default.
