Hello!
I'm developing application uses PG as backend.
A recent stress test found out a serious trouble. Briefly,
libpq does not return control after COMMIT, while
commit actually happened Ok.
It is not quite reproducible: the test hangs during commiting
different transactions. If I terminate PG server,
control returns to application and it goes futher.
It happens against PostgreSQL 8.1.0 and 8.1.1
on Windows and on Linux on several boxes
with different configurations. PostgreSQL 8.0.x is fine.
This stuff operates with significant amount of data
(database size is about 20Gb).
My own attempts to investigate this issue failed
and I badly need community assistance. The question
is what should be provided to make it possible.
At first glance I should get application
and server core files and may be strace of application
networking with server.
What else?
Do we have a sort of manual could be used in my case?
I can produce log or all PG queries, but [as far as I understand]
it is not enough to replay at least because PG does not put in log
values of bound parameters.
Many thanks.
