Thanks.
I had forgotten the Execute / Format way and I thought a parameter is an identifier.
Generally the docs are concise and easy to understand.
Maybe the doc for SET ROLE doc could say something like 'See <link example> for execution inside a function'

While this is documented (last para of "42.11.1. Variable Substitution"),
it's not exactly prominent. Should we move that to somewhere more
visible? If so where?
I think the docs are acceptable as-is - especially given the numerous cross-references to that section. If anything i’d maybe call out that most non-result returning commands are actually not parameterized in “42.2.5 Executing a Command with No Result” just before the link to 42.11.1
