I enjoy another technique that's not exactly embedding but makes the
sql file easily executable from other shells to and easier to
maintain (eg. you don't lose syntax highlight, you don't need to
make wide use of x bit, you can concatenate files...).
echo "select :a;" | psql --set a=3 test
?column?

3
(1 row)
of course in spite of piping your sql, you could put it into a file.
