Transaction is a logical block. You can do whatever you want within one transaction.
For example, for one functions of our product we build a temporary table, insert a set of tuples there and then run a
SELECTthat uses that temporary table and a permanent table. All that stuff is inside a transaction which is rolled back afterwards so that no changes happen to the database.
