Thank you.
I removed transaction from script as all.
I send every statement separately to Postgres.
So each statement runs in its own single transaction now.
I hope that this does not decrease speed and this is best solution?
Now
explain analyze SELECT r.dokumnr
FROM rid r
LEFT JOIN dok d USING (dokumnr)
WHERE d.dokumnr IS NULL
returs the same time from script and when returned separately in small
database.
