If what you want to do is detect errors and work around them, this will
require nested transactions.

The core care about all our happiness :-)
But there aren't that many of them :-(
But I do know there's interest in getting nested transactions working :-)
But it's not ready yet :-(
But you can help :-)

Firstly - good for you. People like you are the reason PG is such a pleasure
to work with.
Secondly, check the pgsql-hackers list (start with the archives). I don't know
what the state of nested-transactions is, or whether you have enough C
knowledge to help out at this stage.
If you can't help with the code, but you can sync CVS and compile from source,
then you can help testing.
If you don't feel comfortable with that, then there will need to be
documentation written (later) and examples, and articles that can go on
postgresql.org or news sites.

I'm sure you'll be able to move this feature along at some point - if like me,
you lack the C skills to code, you may have to be patient though.
