You might have better luck if you paste the EXPLAIN ANALYZE of the
SELECT INTO here (Maybe a new thread? Maybe on -performance? use your
judgement...). But I bet if its doing something with transactionid
like your straight select was, an index would help. If you are just
using SELECT INTO to copy all of the data into a new table... COPY
might be faster or CREATE TABLE AS.
