BUG #13994: Documentation of pg_notify is incorrect.

The following bug has been logged on the website:

Bug reference:      13994
Logged by:          Peter McGeeney
Email address:      junkmesend@gmail.com
PostgreSQL version: 9.5.1
Operating system:   Windows 8.1
Description:

The documentation at

http://www.postgresql.org/docs/9.5/static/sql-notify.html

Recommends the command...

SELECT pg_notify('fo' || 'o', 'pay' || 'load');

which doesn't work but

PERFORM pg_notify('fo' || 'o', 'pay' || 'load');

does work, as explained here.

Please note that this is nothing to do with the uppercase issue with
pg_notify here...

Many thanks
