Huh.  Digging in the commit history, SESSION_USER was the original
implementation (commit 838fe25a9 of 2002-04-01) but it was changed later
that month (ccfaf9067 of 2002-04-29) when we added schema permissions
checks.  Evidently I forgot to update the docs to match :-(

Will fix, thanks for noticing!
