Must be owner of function

I am using postgresql-odbc and trying to "CREATE OR REPLACE FUNCTION..."
from my C-Application, however, I get "must be owner of function ..." error.
If I execute the command logged in as postgres (i.e. su postgres), then I
can execute the command.  I think I tried to grant privileges to public for
the tables/functions I'm using to no avail.  I also tried to alter function
ownership, but this also gets an error because th function does not exist
yet.

Any help/guidance would be appreciated.

Thanks,
Jerry
