I just wanted to throw this out to the users before I made a complete fool of myself by formally requesting it. But I would like what I hope would be a minor change (enhancement) to the psql command. If you look on this page, https://wiki.postgresql.org/wiki/Shared_Database_Hosting ,
you will see a number of example which look like:

psql -U postgres template1 -f - << EOT

REVOKE ALL ON DATABASE template1 FROM public;
REVOKE ALL ON SCHEMA public FROM public;
GRANT ALL ON SCHEMA public TO postgres;
CREATE LANGUAGE plpgsql;

EOT

To me this looks similar to a UNIX shell script. Now, going sideways for a second, if someone wanted to create a "self contained" awk script. It would look something like:

#!/bin/awk -f
... awk code ...

When a user executes the above from the command line, the UNIX system runs the program in the first "magic" line as if the user had entered "/bin/awk -f ..." where the ... is replaced by the name of the file executed followed by the rest of the command line parameters.

I think it would be nice if psql would do the same, mainly for "consistency" with other UNIX scripting languages, such as python, perl, & gawk.

These languages has defined # as line comment. It is not true for SQL.

​Thanks, that looks like a "NO" vote to me. ​

Pavel
