Driver's SQLAllocHandle on SQL_HANDLE_DBC failed

Hi,

I have compiled unixodbc and postgressql odbc driver on solaris 10 server to
connect to postgressql database and I am having following issues

./isql -vvv DG4ODBC
[IM005][unixODBC][Driver Manager]Driver's SQLAllocHandle on SQL_HANDLE_DBC
failed
[ISQL]ERROR: Could not SQLConnect

Here is the trace file:
