Tom>Note the waffling immediately after that, though.

I assume PostgreSQL switched to Ryu around release 12 or so.

Should float4_numeric switch to Ryu as well?
I guess it would be both faster and more precise.

What is the reason to use different implementations for basically the same
task of converting float to a string?
