Using record.items() method

Hello everyone,

I'm trying to code a function that processes records from various tables performing the same action in each case. The functions receives as an argument a RECORD type variable and I'd like to iterate through each of its elements. According to the documentation here:

http://python.projects.postgresql.org/pldocs/plpython3-postgres-types-record.html

there exists an items() method that returns a set of tuples each with the attribute name and the associated value. How can use this method with pl/pgsql?

Thank you,

Luís
