Yes we would not expect you to use a } in a function name. Is this absolutely necessary ?

Hi,

The function name i used is "test_fu}n2".Yeah,i kown that may be nobody will create a function with some name like this,but, it can be created successfully.Ok, i check the code of jdbc,i found some problem lead to the question above. The code file is org/postgresql/core/Parser.java,and row 603 to row 646,the handle of '}' .

I have no idea if it is necessary to modify it.
