That's a very poor design because it's both denormalized and has very
poor naming. There are likely plenty of other things wrong with it,
too

If you need them one by one
If you need them one by one why fetch them into tmprec? Take a look at
the docs for FETCH:
http://www.postgresql.org/docs/8.3/static/sql-fetch.html
especially the FETCH ABSOLUTE...

Please disregard my other message. I didn't get what you are trying to
do at first.
You can do this with dynamic SQL: Look at 38.5.4. Executing Dynamic
Commands (http://www.postgresql.org/docs/current/static/plpgsql-
statements.html).
I guess something like
EXECUTE 'SELECT tmprec.group' || i INTO
Hello. I have table classif with columns:
... , group1, group2, group3, ... , group48, ...
In function i do query and want run on every row and dynamically operate on
columns from group1 to group20. I do something like this:
OPEN curs FOR select * from classif;
loop
fetch curs into tmprec;
