Re: [GENERAL] pg_query transaction: auto rollback? begin or start?? commit or end???

I was referring to conditions outside the database which you
detect while the transaction is in progress and which
invalidate the semantic integrity of the transaction as a
whole. Under such circumstances you would want to issue a
rollback even though technically the transaction went
through an *could* be committed. That's about the only case
where it makes sense to have a keyword separate from "end",
namely "rollback". Because you have the choice: either "end"
the transaction or "rollback". All other cases just need
"end". They will rollback or commit depending on whether
there were any unhandled errors.
