| Release date: 2002-02-04
Overview
This release improves PostgreSQL for use in high-volume applications.
Major changes in this release:
VACUUM
Vacuuming no longer locks tables, thus 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.
Transactions
There is no longer a problem with installations that exceed four
billion transactions.
OID's
OID's are now optional. Users can now create tables without OID's
for cases where OID usage is excessive.
Optimizer
The system now computes histogram column statistics during
"ANALYZE", allowing much better optimizer choices.
Security
A new MD5 encryption option allows 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.
Internationalization
Program and library messages can now be displayed in several
languages. |
