FYI anyone who wants to have a psql shell script:

select version();

Very cool. And very clever. Thanks.

It should be possible to do things like

#!/usr/local/bin/psql -U someuser -d dbname
select version();

But the current psql implementation doesn't allow that for various
reasons. I don't know if it can be "fixed"...

When bash interprets the magic line starting with #! it appends the filename to the end of
the command, it doesn't pipe the contents of the file to stdin. So when I was trying to
write the shells script first I tried something like

#!/usr/local/bin/psql -U someuser -d dbname -f

but psql couldn't handle the magic line itself, and you can't have pipes in the magic
line, so I finally settled on using tail on the script itself (inspired by the jdk
installers from sun).
