Fedora Update Notification

Name        : postgresql-pgpool-II
Product     : Fedora 11
Version     : 2.2.2
Release     : 1.fc11
URL         : http://pgpool.projects.PostgreSQL.org
Summary     : Pgpool is a connection pooling/replication server for PostgreSQL
Description :
pgpool-II is a inherited project of pgpool (to classify from
pgpool-II, it is sometimes called as pgpool-I). For those of
you not familiar with pgpool-I, it is a multi-functional
middle ware for PostgreSQL that features connection pooling,
replication and load balancing functions. pgpool-I allows a
user to connect at most two PostgreSQL servers for higher
availability or for higher search performance compared to a
single PostgreSQL server.

pgpool-II, on the other hand, allows multiple PostgreSQL
servers (DB nodes) to be connected, which enables queries
to be executed simultaneously on all servers. In other words,
it enables "parallel query" processing. Also, pgpool-II can
be started as pgpool-I by changing configuration parameters.
pgpool-II that is executed in pgpool-I mode enables multiple
DB nodes to be connected, which was not possible in pgpool-I.

Update Information:

Changelog since 2.2:    - In master slave mode, sometimes DEALLOCATE fails. This
is    caused by that the first PREPARE was not executed on the
slave(Toshihiro)    - Update pgpool.spec along with related files(Devrim)    -
Fix inser_lock so that it is ignored when protocol version is     2(Tatsuo)
- Remove excessive log messages regarding parameter change      notice(Tatsuo)
- Add missing files to doc(Tatsuo)    - Ignore write error on frontend
connection. This is needed to    continue processing with backend, otherwise we
risk data    incositency(Tatsuo)    - Fix bug introduced in 2.2.1 (In master
slave mode, sometimes    DEALLOCATE fails). If prepared statement reused, pgpool
hangs(Toshihiro)    - Fix pgpool crash when SQL command PREPARE and protocol
level     EXECUTE are mixed. The bug was introduced in 2.2(Tatsuo)    - Avoid
"unexpected EOF on client connection" error in     PostgreSQL when reset query
