Hi,

how I can get some agregates (avg, min, max) for whole week (in specified
year)?
For example from table with two columns : time datetime and value float8.
And I want to get average of value based on whole weeks. If I try to use
date_part('week',time) - Postgresql doesn't recognize word 'week'.

    Thanks   Karel
