pgagent + faikure + Bug

Hy folks,

First I foud a bug.
While I edit a jod and try to modify a step or a schedule from this
window, pgadmin crashed as I validate.

Then I have a probleme with the syntax of the steps.
I created a function that is called each night : fn_myfunction (returns
void)
When I exexute select fn_myfunction(); in the sql panel, everything is
good.
Unfortunately as I copy this command in the detail of the job, it's
always unsuccessfull.
The message is : function fn_myfunction doesn't exists
Yet it exists in the database as I could run the command directly. What
kind of issue could it be?
I work on a local database. In the job, I precised the database I work
with.

Thanks for your help
