Hi,
I am not sure what you mean, I am not a developer.
What I did:
started gdb and then:
(gdb) set pagination 0
(gdb) attach 84465
Attaching to process 84465
0x00007f58bd33143e in __libc_read (fd=0, buf=0x7ffe09e53c80, nbytes=1)
at ../sysdeps/unix/sysv/linux/read.c:27
27 ../sysdeps/unix/sysv/linux/read.c: No such file or directory.
(gdb) continue
Continuing.
[Inferior 1 (process 84465) exited normally]
(gdb) backtrace full
No stack.
(gdb) quit
that's it.
I think I have to get a stacktrace of the postgres server process , not
of psql but I do not how to do that.
