Crikey!  You're right.  I need to be more careful with my assumptions.

I maintain that people need to be more careful with pg transactions.
I've seen several posts about "idle in transaction".  But its not as bad
as I made out.  My confusion comes from the library I use to hit PG,
which fires off a "begin" for me, and if I dont explicitly commit, it
gets rolled back.

sorry, it was confused between framework and PG.
