vsql exit status for "No such file or directory"

Maybe check if the file exists prior to running vsql?

Example:

[dbadmin@localhost ~]$ FILE=/home/dbadmin/run_me.sql

[dbadmin@localhost ~]$ ll $FILE
ls: cannot access '/home/dbadmin/run_me.sql': No such file or directory

[dbadmin@localhost ~]$ [ -f $FILE ] && vsql -f $FILE || echo "$FILE does not exist."
/home/dbadmin/run_me.sql does not exist.

[dbadmin@localhost ~]$ echo "SELECT 1 AS some_column;" > $FILE

[dbadmin@localhost ~]$ [ -f $FILE ] && vsql -f $FILE || echo "$FILE does not exist."
 some_column
-------------
           1
(1 row)

Maybe check if the file exists prior to running vsql?

1. We do that. But this is workaround. And such trick didn't saves us if file became unavailable after check and before vsql starts.
2. What about included files? Same problem. We do another check via parsing of output. But this is weird.
   Process must return correct exit code. All programs do that.

Sorry for some toxic in my opinion )
