Well, actually there is.
Do the processing in a plperlu function which uses it's own connection to the db. Then every instance of the function will have it's own transaction.
Try to start that perl connection outside the function or your performance will drop too much.
I use this technique to fetch, process and store records from an oracle db (erp) in a postgresql db (datawarehousing/reporting/external data).
It gets me some 500,000 records in little over 50 minutes.
Probably real perl addicts would have a lot to say about my coding, but being a perl illiterate (does one write it like this?) I must say that I'm quite happy with the result.
All I used was the perl chapter in the postgresql manual (big hurray for the manual), perl express for testing and debugging of a lot of very
basic things like hashes (yes, illiterate !-) and EMS SQL Manager.
Good luck
