The new driver switched from non-prepared statements to prepared statements. The logging is different in each case and is useful because you can compare similar SQL statements more easily than before. You should hopefully have noticed a performance improvement also with prepared statements. Logging parameter values is likely to be there for 8.2, but I don't think that is likely to be back-ported to 8.1. Could you say how you'd *like* it to work in detail, so we can get some opinions on how best to implement this. I've posted an initial design about a month ago on -general but without much response. > When I connect to postgres from PHP or Python or using just psql, I can > see full SELECT querries logged, with the actuall values for the > parameters. Those interfaces do not use prepared statements, so are not logged in the same way. Best Regards, Simon Riggs
