No, it's not the example but the operator description, and what it says is "string || non-string or non-string || string" so it's trying to illustrate that there are two options: string || non-string non-string || string but maybe it's not super-clear about that. This is much clearer in the docs for Postgres 13, which has been heavily reformatted: https://www.postgresql.org/docs/devel/functions-string.html -- Álvaro Herrera https://www.2ndQuadrant.com/ PostgreSQL Development, 24x7 Support, Remote DBA, Training & Services
