psql \df+ [pattern] with overloaded functions

Using psql, how can I use specify a pattern for \df+ to only show a
single overloaded function. The following is a list of my overloaded
functions, and following this is an example what what happens when I
try to limit the list by including the function signature.

instrumentation=> \df update_history*
