Обсуждение: File Groups with postgresql

I'm not sure if this is the right forum for this question, but here goes.

I am trying to create a database with a preallocated amount of storage (eg.
Filegroups in SQL Server).
Is this possible with postgresql or is there an equivalent.

No, PostgreSQL is not pre-allocating space.
This is definitely not a bug.
If you want that you should use a separate filesystem partition which
can grow on demand.
