handle a ECPG_bytea typo

[Wang, Shenhao]

Hi, hackers

The source looks like:

        case ECPGt_bytea:
        {
                struct ECPGgeneric_varchar *variable =
                (struct ECPGgeneric_varchar *) (var->value);

                ......
        }

I think the developer intend to use struct ECPGgeneric_bytea instead of struct 
ECPGgeneric_varchar

Is this thoughts right?

I have wrote a patch to fix this typo
