Hi,
Please find attached patch with fix.
*Changes:*
1) Take a list of "function argument types", create a string separated by
comma(removing trailing comma).
2) Function arguments in ALTER and GRANT not necessarily to have *argument
mode, name, *they are optional. Only type is required.
Now GRANT statement is represented as
*GRANT EXECUTE ON FUNCTION test_schema.test_func(integer, integer, integer)
TO postgres *as in pgadmin3.
Please review.
