Transaction blocks

[Jonathan Barnhart]

Is there a way to continue a transaction after an error? I've got a
situation where I have a transaction open and I'm inserting data, but
some of it could fail on validation. I want to keep the good stuff,
leave out the bad, and get the speed of not having to commit every
record seperately. For a specific example, I'm importing a list of
stocks, but some symbols have changed because the list is old, so there
are invalid symbols in the list that are not found in the master list.
I want to catch the invalid ones and fix them, but still commit the
good ones. Right now I'm committing each record, but it's slow.

TIP 9: the planner will ignore your desire to choose an index scan if your
joining column's datatypes do not match

That feature (save points / nested transactions) will be in 8.0, which
just entered beta, however, it will still have the issue that you'll be
making a bunch of transactions, so to speak, so the speed likely won't
be better, just the error handling for what you're trying to do.
