I intentionally used elog() because I thought single user mode is not user-facing.
But it is OK for me to use ereport() instead.

Single-user mode is also known as "Oh crap!" mode, something used when starting the server in multi-user model fails for non-trivial reasons.

It is also what at least one PostgreSQL Online Service (a.k.a. fiddle) uses as an implementation choice.
