You *are* trying to be contentious.
In PostgreSQL, there are psql variables, but no SQL variables.
You may not like that, that's okay. But that's how it currently
is, and it is documented like that.
If you want that to change, your best option is to review
https://commitfest.postgresql.org/51/1608/
which tries to introduce variables into SQL.
As far as I can tell, the SQL standard knows variables only
as host variables in embedded SQL.
