I think you mis-parsed it. The sentence about PREPARE et al is an
independent sentence applying to all the possible values of
log_statement. That is, these commands will be logged if the contained
command is one that would have been logged, at the current log level.

Ah. Probably you are confusing PREPARE-the-SQL-command, which is what
this is speaking of, with the protocol-level prepared-statement
functionality. 8.1 is pretty bad about logging extended-query-protocol
operations. If you can update to 8.2 you'll be happier.
