However, the error message states that the function fnupdatesalegtab09 does not exist, indicating a mismatch between the function name or the provided arguments.

Cause

The cause of the error is likely due to a typo when defining or calling the function, or incorrect argument types.

Solution

To resolve this error, you should:

1. Ensure the Function Name is Correct: Double-check the spelling of the function name, including capitalization, and make sure it matches the function you intended to call.
2. Verify Argument Types: Check that the provided arguments match the data types defined in the function signature. In this case, specific attention should be paid to the smallint parameters, as numeric literals might be incorrectly interpreted as integers if not explicitly cast.
3. Cast Arguments Explicitly: To ensure the correct data types are used, consider explicitly casting the numeric literals to smallint using the syntax: '12'::smallint.

By following these steps, you can ensure that the correct function is called with the expected argument types, eliminating the error.
