The command line parser inside psql works pretty much like a Unix shell.
That means quoting and escaping is resolved *before* the arguments are
passed to the command.  So when you enter

\f '\t'

then the parser resolves this as two tokens: the first is <backslash><f>
and the second is <tab character>.  The \f command and ultimately the
routine that sets the field separator have nothing to do with that.

I believe this design is ok, even though it creates apparent
inconsistencies.  If you make it behave like you appear to imagine, then
you need to double-escape certain characters in situations where other
users might not expect it.
