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.
