Pre-allocate space in advance

Title: Vacuum Verbose output

I apologize for the wrong subject in a previous post. Here it is again:

 

 

  My understanding that the current release of Postgres does not allow the DBA to pre-allocated space for the data files or tablespace in advance (as Oracle or SQL Server does). Am I correct on that ? If that's still the case, is this item on the TODO list or the white board? Pre-allocating space will prevent extending the datafile during loading massive data (batch processing) and would improve the overall batch write performance.

 

Thanks in advance.
