I presume this is similar to JDBC's use of server side prepare. If so do you see a performance problem with servers older than 9.2 since Tom's fix to planning prepared statements is only in 9.2 and above ?
The docs on ODBC configuration options recommend UseServerSidePrepare=1 for server versions 7.4 and above. That's a good recommendation. Given that "7.4 and above" covers all supported versions of PostreSQL, and every reasonable version people might want to use a new driver with, how about we make UseServerSidePrepare=1 the default, so that people don't need to set it manually?
I hear no objections, so committed. UseServerSidePrepare=1 is now the default, for the upcoming driver version 9.3.X.
