timestamp

A tough SQL question (I'm using postgres by the way).

I need the first row inserted every day for the past X days. one of my columns is a timestamp, which i hold the time inserted, and another column is the row id.

If it's not possible to get the first row inserted every day, i at least need a unique one; a single row for every day for the past x days.

Any suggestions?

Thanks
