Well, this is pretty interesting:

open("/dev/tty", O_RDONLY)              = 3
open("/dev/tty", O_WRONLY|O_CREAT|O_TRUNC, 0666) = 4
ioctl(3, SNDCTL_TMR_TIMEBASE or TCGETS, 0x7fffc631e550) = -1 ENOTTY
(Inappropriate ioctl for device)
ioctl(3, SNDCTL_TMR_CONTINUE or TCSETSF, {B0 -opost -isig icanon -echo
...}) = -1 ENOTTY (Inappropriate ioctl for device)
fstat(4, {st_mode=S_IFREG|0644, st_size=0, ...}) = 0
mmap(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) =
0x7fb252e41000
write(4, "Password: ", 10)              = 10
fstat(3, {st_mode=S_IFREG|0644, st_size=10, ...}) = 0
mmap(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) =
0x7fb252e40000
read(3, "Password: ", 4096)             = 10
read(3, "", 4096)                       = 0
read(3, "", 4096)                       = 0
ioctl(3, SNDCTL_TMR_CONTINUE or TCSETSF, {B0 -opost -isig icanon -echo
...}) = -1 ENOTTY (Inappropriate ioctl for device)
write(4, "\n", 1)                       = 1
close(3)                                = 0
munmap(0x7fb252e40000, 4096)            = 0
close(4)                                = 0

It *is* prompting for a password, or so it thinks.  Apparently /dev/tty
is connected to the bit bucket in your environment?

                        regards, tom lane

I've been bit where foreground colour == background colour.
