Summary: Cannot insert very large blobs

Initial Comment:
I can use the PostgreSQL ODBC driver to insert a blob (bytea) of 128 megabytes, but when I try to insert one that is
399megabytes it fails with: 

Query buffer overflow in copy_statement_with_parameters

The actuall call that fails is SQLExecute.


Here is the snippet of code I see in convert.c:

enlarge_query_statement(QueryBuild *qb, size_t newsize)
{
    size_t    newalsize = INIT_MIN_ALLOC;
    CSTR func = "enlarge_statement";

    if (qb->str_size_limit > 0 && qb->str_size_limit < (int) newsize)
    {
         < here is the branch that is executed>
