I'm looking for info about the synching and I don't see any. Is there a more specific URL and is there a time frame for this. Also, has segmentation been discussed? -----Original Message----- From: pgsql-general-owner@hub.org [mailto:pgsql-general-owner@hub.org]On Behalf Of Peter Eisentraut Sent: Tuesday, October 10, 2000 1:08 PM To: Marc SCHAEFER Cc: pgsql-general@postgresql.org Subject: Re: [GENERAL] Some advanced database features, are they present in PostgreSQL Marc SCHAEFER writes: > - log all transactions to a special log file, that can be used for > backup purposes: Will be in 7.1. > - hard transactions: cutting the power to a PostgreSQL server > may cause data loss and/or data corruption.
