Yup. Those words (and other words that can start a plpgsql statement)
are reserved so far as plpgsql is concerned.

It is not the business of that page to document the behavior of plpgsql.
Perhaps the plpgsql chapter should document what it considers to be
reserved words, but for now, you could look at the list in
http://git.postgresql.org/gitweb/?p=postgresql.git;a=blob_plain;f=src/pl/plpgsql/src/pl_scanner.c

That would require giving plpgsql a privileged position over all other
PLs, which isn't going to happen ...
