odbc parameters

Hello,

I use MS Access for data import. Access imports csv file, make some
calculation and transffers data to PostgreSQL.
Unfortunately, it takes a lot of time to transfer data to PostgreSQL.
My odbc settings are following:

[ODBC]
DRIVER=PostgreSQL Unicode
UID=postgres
XaOpt=1
LowerCaseIdentifier=0
UseServerSidePrepare=1
ByteaAsLongVarBinary=0
BI=0
TrueIsMinus1=0
DisallowPremature=1
UpdatableCursors=1
LFConversion=1
ExtraSysTablePrefixes=dd_
CancelAsFreeStmt=0
Parse=1
BoolsAsChar=0
UnknownsAsLongVarchar=0
TextAsLongVarchar=1
UseDeclareFetch=0
Ksqo=1
Optimizer=1
CommLog=0
Debug=0
MaxLongVarcharSize=8190
MaxVarcharSize=255
UnknownSizes=0
Socket=4096
Fetch=100
ConnSettings=
ShowSystemTables=0
RowVersioning=1
ShowOidColumn=0
FakeOidIndex=0
Protocol=7.4-1
ReadOnly=0
SSLmode=allow
PORT=5432
SERVER=localhost
DATABASE=PLANINGZ

Could you suggest what parameters values would yield best performance for
batch import to PostgreSQL?

Thanks.
