Looking at the strace report that someone has sent me before, there is a
problem with devices:

===================================================================
<snip>
fstat64(1, {st_mode=S_IFCHR|0666, st_rdev=makedev(1, 3), ...}) = 0
ioctl(1, SNDCTL_TMR_TIMEBASE or TCGETS, 0xbfe16a8c) = -1 ENOTTY
(Inappropriate ioctl for device)
mmap2(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1,
0) = 0xb7dee000
write(1, "pg_dump dumps a database as a te"..., 2367) = 2367
munmap(0xb7dee000, 4096)                = 0
exit_group(0)                           = ?
===================================================================

This one is from a server with SELinux enabled. My server does not produce
this, and uses virtual console (as expected?). However with SELinux
enabled, it wants to use ramdisk (expected? I think no...)
