Any tool/script available which can be used to measure scalability of an application's database.

Dear @,

Is there any tool or some sort of script available, for PostgreSQL, which
can be used to measure scalability of an application's database. Or is
there any guideline on how to do this.

I am a bit confused about the concept of measuring scalability of an
application's database.

How is the scalability measured?

Is it like loading the DB with a bulk data volume and then do performance
testing by using tools like JMeter?

Could any one kindly help me on this..

Thanks,
Sreejith.
