Do not read neither the system-wide psqlrc file nor the user's ~/.psqlrc file

During unknown tables check there is error:

Reading database options from /etc/zabbix/zabbix_server.conf...
Configuration:
- type: psql
- host: 127.0.0.1 (127.0.0.1)
- port: 5432
- database: zabbix
- user: zabbix
- output: /tmp/tmp.tzM4s7yilr
Fetching list of existing tables...

ERROR
Unknown tables found in database:
- Time:
- 7.813
- ms
To include them (full data backup) specify -f, to ignore them use -i

It happens because I use \timing in ~/.psqlrc to see how long each query takes.

Adding --no-psqlrc solves the issue.

maybe you should add an option to enable/disable this behavior, rather than always disabling?

@ironbishop, thanks for comment.
IMO backup software should just work, in case of bath mode, it should not rely on local user preferences.
I would prefer to leave this PR as-is, if it's possible.

btw, there is duplicate: #25

There is, and it's missing the cli option the same way. Can you add it?
