Thank you.
I could apply them against 93_STABLE and build it.
(commitID: d32e8387bac15ad353029c259e832f78d456c7a8)
deadlock did not occur with my test case.
It seems these patches resolve my problem.
If it doesn't have any other problems,
would you commit them for next release(9.3.2)?
FYI:
These patch doesn't resolve bug#8470 yet.
I could reproduce the problem on patched PostgreSQL.
regards,
