Stumped: is there any way to set up default values for psql variables
within the .SQL file itself? Obviously, I can do something like:

$ psql -f my_script -v MYVAR=${myvar:-mydefault}

but I would prefer to have the value stored with the .SQL file, e.g. (if
this actually worked):

\set MYVAR COALESCE(:MYVAR,'mydefault')


Stuff like this works for me in a SQL file....

\set edate 'CURRENT_DATE::DATE'

SELECT * FROM some_table WHERE update_date = :edate;

Sure, but that was not my question. I want to be able to set the variable on the command line, BUT have it default to a value inside the SQL script if not present on the command line.

$ psql -v edate=2004-01-01 ... => \set edate 'CURRENT_DATE::DATE' => select :edate; date ------------ 2006-01-14
