In the PL/PgSQL documentation, section "40.6.4. Looping Through Query
Results" [1]
contains a sample function which refreshes pseudo-materialized views. As 9.3 has
proper materialized views, I thought it could do with updating. There
was also an erroneous
"%s" in a RAISE NOTICE, and I've tweaked the function definition a bit
to increase its
usefulness as a sample.
