+
+
+Release 7.2 (2001-??-??)
+
+
+This release improved PostgreSQL for use in high volume applications.
+
+Major changes in this release:
+
+ VACUUM - VACUUM no longer locks tables, allowing normal user
+access during the VACUUM. A new VACUUM FULL command does old-style
+vacuum by locking the table and shrinking the on-disk copy of the table.
+
+ Security - A new MD5 encryption option allows much more secure
+storage and transfer of passwords. A new unix-domain socket
+authentication option is available on Linux and *BSD systems.
+
+ Statistics - Administrators can use the new table access
+statistics module to get fine-grained information about table and index
+usage.
+
+Migration to 7.1
+
+ A dump/restore using pg_dump is required for those wishing to migrate
+ data from any previous release.
