I guess you can  use nested blocks in side a function(BEGIN,END) but not
commit   because a SQL function  runs as a single transaction.

He could use SAVEPOINT to do something similar -

  http://www.postgresql.org/docs/8.2/static/sql-savepoint.html

- though it might or might not work for him, depending on his needs.

if you want to break plpgsql function, use exceptions. That will cause
transaction (which in it self is the whole procedure) to be rolled
back.
