I have recently installed postgresql 9.1 after uninstalling postgres 9.3 as per the requirement of my project but I am not able to run basic sudo command with postgres user.
我最近安装了postgresql 9.1，根据我的项目的要求卸载了postgres 9.3，但是我不能使用postgres用户运行basic sudo命令。
sudo -u postgres -h localhost createdb template_postgis
This gives me no error but shows the usage of sudo:
这没有给我错误，但是显示了sudo的用法:
usage: sudo -h | -K | -k | -L | -V
usage: sudo -v [-AknS] [-g groupname|#gid] [-p prompt] [-u user name|#uid]
usage: sudo -l[l] [-AknS] [-g groupname|#gid] [-p prompt] [-U user name] [-u
user name|#uid] [-g groupname|#gid] [command]
usage: sudo [-AbEHknPS] [-C fd] [-g groupname|#gid] [-p prompt] [-u user
name|#uid] [-g groupname|#gid] [VAR=value] [-i|-s] [<command>]
usage: sudo -e [-AknS] [-C fd] [-g groupname|#gid] [-p prompt] [-u user
name|#uid] file ...
Though sudo works for other projects and commands but not in this. It was working earlier perfectly. I will be really thankful if someone helps.
虽然sudo在其他项目和命令中工作，但不是在这方面。它工作得更早了。如果有人帮忙，我会非常感激的。

In the manual page for sudo (which you can view by running man sudo in the terminal), you can see that this is exactly what the -h option does:
在sudo的手册页面中(您可以通过在终端运行man sudo查看)，您可以看到这正是-h选项所做的:
-h The -h (help) option causes sudo to print a usage message and exit.
You should be able to run the command without that option:
您应该能够在没有该选项的情况下运行该命令:
sudo -u postgres createdb template_postgis
