This is not DBI/DBD-Pg specific.

A short test with psql shows, that this seems to be 
a bug of postgresql itself.

Create and fill a database. Connect to this database with psql
and perform some query. Without disconnecting destroy and re-create 
the database but insert this time different data. Performing
the same query a second time will retrieve the same data as before
