Hmm, it looks like \df does not cope well with spaces in the argument
list:

regression=# \df genome_threshold_mono(text,text,double)
                       List of functions
 Schema | Name | Result data type | Argument data types | Type 
--------+------+------------------+---------------------+------
(0 rows)

regression=# \df genome_threshold_mono(text,text, double)
ERROR:  invalid regular expression: parentheses () not balanced

It's sending the server a bogus pattern in the second case.
I've not looked at the code yet, but this does seem like a
psql (not server) bug.

As Adrian noted, you're not supposed to use parameter names
in \df, only their types.  It seems like whitespace ought
to be allowed though.
