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.
