I 'm storing things in a table with now() and I want to select * from
theTable WHERE the Timestamp is > the current time - 20 minutes
Anyone know the correct syntax. I was trying something like:
WHERE timestamp_field > (timestamp now() - interval '20 minutes')
and will continue reading the manual

TIP 9: In versions below 8.0, the planner will ignore your desire to
choose an index scan if your joining column's datatypes do not
match
