No I did not do it in on transaction (although in .net I never started or
commited a transaction.
ODBC :myTrans = myConnection.BeginTransaction(IsolationLevel.ReadCommitted)
' Assign transaction object for a pending local transactionmyCommand.Transaction = myTrans
'example of insert
'myCommand.CommandText = "Insert into Region (RegionID, RegionDescription)
VALUES (101, 'Description')"
myCommand.CommandText = insertsqltext
myCommand.ExecuteNonQuery()
myTrans.Commit()
.net driver:
Dim cmd As New NpgsqlCommand(insertsqltext, cnn)
cmd.ExecuteNonQuery()
cmd.Dispose()

You *are* using transactions, you don't have a choice. Did you do the
transfer of all 4GB in ONE transaction with the ODBC? Please describe
