Hmm. HPUX's man page for getpass says:
STANDARDS CONFORMANCE
getpass(): AES, SVID2, SVID3, XPG2, XPG3, XPG4
However, it also says:
getpass() reads up to a newline or EOF from the file /dev/tty, after
prompting on the standard error output with the null-terminated string
prompt and disabling echoing. A pointer is returned to a null-
terminated string of at most 8 characters. If /dev/tty cannot be
opened, a NULL pointer is returned.
The 8-char limit is alone sufficient to disqualify it for use in psql.
