Thanks for the quick response,
I had read the documentation but got a little confused with the
phrasing. The option I wanted was CREATEROLE.

"These clauses are an obsolete, but still accepted, spelling of SUPERUSER
and NOSUPERUSER."

I saw obsolete prior to reaching out, but I still did not understand these
clauses had been replaced with SUPERUSER and NOSUPERUSER. Perhaps those
options should be removed from the Synopsis to avoid tempting users.

Overall good work,
I am looking forward to this release.
