As the beginning of this thread shows, I know how to do this with a HERE
document, I was just trying to clean it up.
I am not trying to be contentious, but a simple search shows that every
major implementation of SQL allows variables and there are hundreds if
not thousands of pages dedicated to the idea of using variables in SQL
and how they are fundamental.
There are certainly reasons this doesn't work, but saying variables are
psql specific......
