The shell interprets the double quoted string and effectively replaces $1
with the shell's idea of what to put in place of it. This really has
nothing to do with postgres at all. Use a backslash before the $1, or
put it in a file and execute it from there.
Try these for example:
echo "$1"
echo '$1'
echo "\$1"
