Hi devs,
I came across a hang issue when COPY to a FIFO file, because the FIFO is
not opened for read on the other end. The backtrace from master branch is
like:
#0 0x00332ccc6c30 in __open_nocancel () from /lib64/libc.so.6
#1 0x00332cc6b693 in __GI__IO_file_open () from
necessary to acquire the LWLock?
Thanks,
Kenan

Hi Heikki,
Could you please help provide a case to elaborate why we need the LWLock
here? or could you please tell me to whom should I ask this question?
Thanks,
Kenan

Hi there,
In function ProcSleep, after the process has been waken up, either with
lock granted or deadlock detected, it would re-acquire the lock table's
partition LWLock.
The code episode is here:
/*
* Re-acquire the lock table's partition lock. We have to do this to hold
* off
