Description:        DOCUMENTATION: SELECT synopsis omits RETURNING keyword
Details:

I think the documentation of SELECT should include the keyword 'RETURNING'
in its synopsis.

Also, that at least one example be given on that page.

The text mentions 'RETURNING', so I was surprised not to see it in the
synopsis.

I found examples in the section:
'7.8. WITH Queries (Common Table Expressions)'.
