No. But everything is the way it is for some reason. "This would be a useful feature" and "why do not things work this way" both are excellent approaches to instigating change and obtaining the understanding as to the "why" of how things are. "This is a bug and the solution is simple - though I have never actually coded the PostgreSQL" is a less effective way of doing so. I've already agreed that your idea has merit (maybe not much, but some). However, since it is not that way currently (and the problem is not a new one) there likely exists some underlying reason said feature has not been implemented. I offer, via induction and some experience, that said feature is not in high demand, not as simple as you claim, and in many ways is undesirable - thus no one has taken the time to implement it. You either need a more convincing (and novel) argument or you need to contact someone like PGExperts, 2ndQuadrant, EnterpriseDB (for example and none of whom I am affiliated with) and pay them to implement the feature for you (likely much less expensive than learning C and the codebase and doing it yourself). Given that we are both ignorant on the technical aspects of said feature, and our conversation is getting too pointed, I suggest that you simply wait for a response from someone more qualified and in the meantime (since even if someone coded this feature today it would not be in production release until 9.3) code your ETL according to the best-practice I suggested earlier. If the staging table is too large a burden AND no one volunteers to implement your feature your options have been put before you.
