If you run it like this

 $(psql -v passed_in_var=\'some_value\'  -f script_name)

and arrange for all the script output to be in the form

  var1="value 1" var2="value 2"
  var3="value 3" ...

then var1, var2, etc will be set in bash (or ksh, or the posix shell).
Note that there are no spaces around the equals signs.
