problem ODBC

I connect to postgresql via ODBC.
---------------
String connection:

szDns = "SERVER=" & szHost & ";"
szDns = szDns & "PORT=" & lPort & ";"
szDns = szDns & "UID=" & szUser & ";"
szDns = szDns & "PASSWORD=" & szPassword & ";"
szDns = szDns & "DATABASE=" & szDataBase & ";"
szDns = szDns & "DRIVER={PostgreSQL};"
szDns = szDns & "READONLY=0;"
szDns = szDns & "PROTOCOL=6.4;"
szDns = szDns & "FAKEOIDINDEX=0;"
szDns = szDns & "SHOWOIDCOLUMN=0;"
szDns = szDns & "ROWVERSIONING=0;"
szDns = szDns & "SHOWSYSTEMTABLES=0;"
szDns = szDns & "CONNSETTINGS=;"
szDns = szDns & "FETCH=100;"
szDns = szDns & "SOCKET=4096;"
szDns = szDns & "UNKNOWNSIZES=0;"
szDns = szDns & "MAXVARCHARSIZE=256;"
szDns = szDns & "MAXLONGVARCHARSIZE=65536;"
szDns = szDns & "OPTIMIZER=1;"
szDns = szDns & "KSQO=1;"
szDns = szDns & "USEDECLAREFETCH=0;"
szDns = szDns & "TEXTASLONGVARCHAR=1;"
szDns = szDns & "UNKNOWNSASLONGVARCHAR=1;"
szDns = szDns & "BOOLSASCHAR=1;"
szDns = szDns & "PARSE=0;"
szDns = szDns & "CANCELASFREESTMT=0;"
szDns = szDns & "EXTRASYSTABLEPREFIXES=dd_;"

DbCon.Open szDns
