Dot-slash is not a notation, it's a requisite if you do ( correctly )
not have . in your $PATH.

Anyway, this is a little bit complex, as psql many times needs arguments.

It's been pointed it can be done with a shell script. If you can live
with a little noise you can have it dual ( The \r makes it ignore the
previous lines, the \q makes it exit before reading the EOF line ):

~/tmp $ cat kk.sql
#!/bin/bash
psql service=redacted <<EOF
\r
select 2*3*7;
\q
EOF
~/tmp $ psql -f kk.sql service=redacted
Query buffer reset (cleared).
 ?column?
----------
       42
(1 row)

~/tmp $ psql service=redacted < kk.sql
Query buffer reset (cleared).
 ?column?
----------
       42
(1 row)

~/tmp $ ./kk.sql
Query buffer reset (cleared).
 ?column?
----------
       42
(1 row)
