[ODBC] UseServerSidePrepare not working on aix

I’m getting an error like the connection was dropped trying to read data.

ERROR: CLI open cursor error: Could not receive the response, communication

       down ??

9.6.031 driver using 9.4.12 libpq.

I have to turn off UseServerSidePrepare to get a successful read.

Anyone run into anything like this?  I wondering/hoping if it is something simple like a configure option or something at build time.

Thanks,

Keith
