Hmm, that's weird ... [ cut ... paste ... ]

...
CREATE FUNCTION
regression=# select float8_jitter_add('{.1,.2,.3,1}', 5);
ERROR:  function float8_jitter_add("unknown", integer) does not exist
HINT:  No function matches the given name and argument types. You may need to add explicit type casts.

[ think ... ]  Oh.  You are creating float8_jitter_add(float8[], interval)
whereas this call is going to invoke float8_jitter_add(float8[], integer)
or something compatible with that.  You're seeing a syntax error in a
different, pre-existing function with a similar name.

FWIW, 8.0 has a number of improvements in error reporting that will
hopefully make this sort of problem more transparent.
