RHBA-2005:684 - Bug Fix Advisory
Synopsis
rh-postgresql bug fix update
Type/Severity
Bug Fix Advisory
Topic
Updated rh-postgresql packages that fix a performance problem on AMD64 and
Intel EM64T machines are now available.
Description
PostgreSQL is an advanced Object-Relational database management system
(DBMS) that supports almost all SQL constructs (including
transactions, subselects and user-defined types and functions).
The original release of rh-postgresql did not have assembly-code spinlock
support for AMD64 and Intel EM64T architectures. Instead it used kernel
semaphore calls, which are far slower. Also, the number of semaphores
needed might exceed what the kernel is configured to allow, resulting in
database startup failure.
This update resolves this problem by back-porting AMD64 and Intel EM64T
support from later PostgreSQL releases.
Users of rh-postgresql on AMD64 and Intel EM64T are advised to upgrade to
these updated packages.
Solution
Before applying this update, make sure all previously released errata
relevant to your system have been applied.
This update is available via Red Hat Network. To use Red Hat Network,
