Which really gains me nothing over just:

$ psql -f myscript.sql -v "MYVAR=${myvar:-default}"

The original question was: how can I store the default value in the
"myscript.sql" script where it's used, rather than have it in a calling
script? The aim here was to put the default in the code, so they would
be bound together...
