Even if they are recompiled, they will fail.
switch (sqlvar_struct.sqltype)
{
case ECPG.int: break;
case ECPG.char: break;
/* There is no case for ECPG.bytea */
default: abort();
There is an idea as following, but it seems to be ugly.
Implement a parameter for ecpglib.
The parameter means whether application want to receive
bytea data in binary format or not. Default is "not".
# I don't know any ecpglib's parameter like it.
In other words, if application uses "bytea" type host variable,
ecpglib could know its intent, but in case of sqlda ecpglib could
not know it.
