Bug reference: 6423
Logged by: Weiyu Zhao
Email address: 139669962(at)qq(dot)com
PostgreSQL version: 9.0.6
Operating system: Redhat 5.5 x86_64
Description:
The parameter max_standby_streaming_delay does not work. The parameter is
set 30s. My queries' duration is about 7 or 8 seconds. I still encounter
errors:
CSTFATAL: terminating connection due to conflict with recovery
CSTDETAIL: User query might have needed to see row versions that must be
removed.
CSTHINT: In a moment you should be able to reconnect to the database and
repeat your command.
I have a test case, but I don't know how to upload it.
