Typical Issues

Symptom: Users encounter the following exception when calling a stored procedure, even though they have bound input parameters of a user-defined type and registered output parameters for the procedure:
```
ERROR: Function public.test_proc(compfoo, public.compfoo_table, compfoo, public.compfoo_table) does not exist.
  ???No function matches the given name and argument types. You might need to add explicit type casts.
```
Cause: The user-defined type bound to the input and output parameters does not match the one set in the stored procedure.

Solution: Keep the user-defined type bound to the input and output parameters consistent with the one set in the stored procedure.
Symptom: Users encounter the following exception when calling a stored procedure, even though they have bound input parameters of a user-defined type and registered output parameters for the procedure:
```
java.lang.RuntimeException: org.postgresql.util.PSQLException: ?? CallableStatement ????????????? java.sql.Types=1111 ?? 1?????????? java.sql.Types=2002?
```
Cause: The enableGaussArrayAndStruct parameter is set to true when pgArray compatibility is in effect. However, it is impossible to maintain compatibility with both pgArray and GaussArray simultaneously.

Solution: When pgArray compatibility is in effect, check for and delete enableGaussArrayAndStruct=true.
