Try removing the keyword "interval" (i.e., EXTRACT(MINUTE FROM TestRunTime)). Since TestRunTime is a column name, I think if you wanted to cast it as an INTERVAL you'd specify EXTRACT(MINUTE FROM TestRunTime::INTERVAL), but since TestRunTime is already an INTERVAL, the cast is redundant.

Hello,
How can one pass a non string literal interval to the extract function?
For example:
SELECT starttime, extract(minute from interval testruntime) as runtime from ( select age(endtime, starttime) as testruntime, ref_testnames_serial, starttime, endtime, dense_rank() over (order by starttime desc) dr from dtprfrm764.orion_tests where ref_testnames_serial = 389 and pass = true) x WHERE dr <= 20 ORDER BY starttime asc
Does ‘minute from interval’ only accept string literals?
Thanks,
Adam
