Here's one way; I'm not sure if there may not be something more
efficient, though:
junk=# select sum(if) from i;
sum
----------
00:45:28
(1 row)
junk=# select extract (minute from sum(if)) * 60 + extract (second
from sum(if)) from i;
?column?
----------
2728
(1 row)

========================================
"And he said unto his disciples, Therefore I say unto
you, Take no thought for your life, what ye shall eat;
neither for the body, what ye shall put on. For life
is more than meat, and the body is more than clothing.
Consider the ravens, for they neither sow nor reap;
they have neither storehouse nor barn; and yet God
feeds them; how much better you are than the birds!
Consider the lilies, how they grow; they toil
not, they spin not; and yet I say unto you, that
Solomon in all his glory was not arrayed like one of
these. If then God so clothe the grass, which is to
day in the field, and tomorrow is cast into the oven;
how much more will he clothe you, O ye of little
faith? And seek not what ye shall eat, or what ye
shall drink, neither be ye of doubtful mind.
But rather seek ye the kingdom of God; and all these
things shall be added unto you."
Luke 12:22-24; 27-29; 31.
