Hi

I am new to PostGres and I am evaluating it for our purposes. The biggest
requirement I have is that I need the ability to constantly add columns
dynamically to a table. How is the efficiency of such an operation ?
Basically the number of columns differ per key. Are there any techniques
that are available with Postgres for such operations ?

Thanks
A
