Ah, I see. There was a recent change to make sure shared_preload_libraries
are loaded in single-user mode (6c31ac0), but those are for load at "server
start" instead of "connection start." However, AFAICT
session_preload_libraries is loaded in single-user mode today, and
single-user mode is arguably a connection, so my instinct is that we should
continue to process it in single-user mode. I suppose we might be able to
add more hacks to load it in single-user mode without a new argument, but
at that point, we're probably not too far from your original proposal.
Given all this, I think I'm inclined for the new argument.
