Unless most of your database information is "volatile"(case in which you should implement an automatic cleanup cron), the only remaining option is to get a larger disk for your vps.

Cleanup some space on that device. Maybe your "pg_log" folder has some space to free. If that doesn't helps, you may need to forcefully add more space. There's not really much alternatives there.

Dear Expert,
My PostgreSQL database got down due to no space left on my mount point /dev/vdb1 where my data directory are available, please suggest what's the best solution to resolve this issue. I am also not able to start my database again due to no space available. And right now, we don't have any further space to add in this mount point.

I strongly suggest you take the following additional steps.
1. Add an additional large hard drive and make a tablespace on it.
2. Move a few of your larger tables to the new tablespace.
