SetPos with data_at_exec not yet supported ?

Hi,

I have the following error message in the log file of my driver:

PGAPI_BindParamater: ipar=6, paramType=1, fCType=-2, fSqlType=-4,
cbColDef=-4, ibScale=-1, rgbValue=-1073755584, *pcbValue = -104,
data_at_exec = 1
SC_get_error: status = 15, msg = #SetPos with data_at_exec not yet
supported#
             szSqlState = '07005',len=42, szError='SetPos with
data_at_exec not yet supported'

I like to update BLOB data in the current row of my statement.

What version is capable of data_at_exec using SQLSetPos and also
support full cursor support ?
(not only forward cursors)

I am still using 07.03.0200 on Mac OS X. I didn't get compiled the
07.03.0260 version due to missing
pg_config.

Thanks, Lothar
