Have you tried running it from the command line? Open your favorite terminal program, authenticate as root (if you haven't already), then enter the following (the # shouldn't be typed, it's just a placeholder for the prompt):
# cd /root # chmod +x postgresql-9.1.4-1-linux-x64.run # postgresql-9.1.4-1-linux-x64.run EDIT
You can google the error for yourself, but there are a couple of options. One is that /tmp may be mounted as noexec. Type man mount and check the options to remount it without that option. You can also try to chown root postgresql-9.1.4-1-linux-x64.run and see if that works.
Another potential issue may be with the file's encoding. If you downloaded it in windows, then copied it to Linux, or if you downloaded it from a mis-configured Windows server, it may have CR/LF line endings instead of the Unix standard LF-only newline. There's a utility called dos2unix that may help, if the file is plain text, but make sure you make a backup before trying it, as it may contain binary data as well.
In summary:
# mount -o remount exec /tmp # chmod +x postgresql-9.1.4-1-linux-x64.run # ./postgresql-9.1.4-1-linux-x64.run # mount -o remount noexec /tmp
