blatantly a bug in the documentation

I hope this is the right place to report a bug/issue in the official
documentation...

In
http://www.postgresql.org/docs/current/interactive/plpgsql-control-structures.html
there is an example for a function, cs_refresh_mviews(), chapter 38.6.4.
Within this function there are a "PERFORM cs_log('Refreshing
materialized views...');", but such a function cs_log() are not in the
core distibution.

I think, this is a problem for users which read the doc and try to
reproduce the example or write own code based on the example.

Regards, and many thanks for PostgreSQL to the developer, Andreas
