The following documentation comment has been logged on the website: Page: https://www.postgresql.org/docs/14/sql-set.html Description:
A reader of this section https://www.postgresql.org/docs/current/sql-set.html of the documentation might be forgiven for thinking that Postgres does not support custom variables. There are also related commands and features that are not mentioned. These might be covered by a reference to 20.1.3, but that section also does not mention custom variables afaict. I'd be happy to write some better documentation (for all the sections in question). I think actually a separate section under 20.1 that could be referred to from SET, SHOW etc might be best. I've contributed to the documentation before, but I forget how. A description of how at the bottom of the Documentation home page or at least in the FAQ might be in order also.
