let us consider the following test case. There are two tables T1 that has 
int and varchar fields and T2 that has varchar, datatime and blob fields. 
Then we have a query batch like this:
select * from T1;
select * from T2

It executes with ODBC and gets the first recordset as expected. But then I 
have problems. SQLMoreResults says there is another recordset. 
SQLNumResultCols says there are 3 columns indeed. But subsequent 
SQLDescribeCol calls return wrond descriptions. The first call for it says, 
for example, that the first field of the second recordset is of type 
SQL_INTEGER while I expect it to be varchar. And subsequent SQLFetch fails.

I use the latest PostgreSQL 8.2 binaries for Win32.

So, does current PostgreSQL ODBC driver supports query batches and 

Thank you in advance,
