... and I can't figure out why ...

I added a bunch of debugging to SYSLOG to trace it, and it comes down to:

Jul 30 10:01:45 nrelay PAM_pgsql[37016]: options_valid: top
Jul 30 10:01:45 nrelay PAM_pgsql[37016]: options_valid: bottom
Jul 30 10:01:45 nrelay PAM_pgsql[37016]: attempting to authenticate: scrappy

Which corresponds to:

    SYSLOG("attempting to authenticate: %s", user);

    if((rc = pam_get_pass(pamh, &password, PASSWORD_PROMPT, std_flags)
        != PAM_SUCCESS)) {
    SYSLOG("attempting to authenticate - in : %s", user);
        free_module_options(options);
        return rc;
    }

    SYSLOG("attempting to authenticate - post : %s", user);

I added some debugging to pam_get_pass, as follows:

int
pam_get_pass(pam_handle_t *pamh, const char **passp, const char *prompt,
    int options)
{
    int retval;
    const void *item = NULL;

    SYSLOG("pam_get_pass: top");
    /*
     * Grab the already-entered password if we might want to use it.
     */
    if (options & (PAM_OPT_TRY_FIRST_PASS | PAM_OPT_USE_FIRST_PASS)) {
        if ((retval = pam_get_item(pamh, PAM_AUTHTOK, &item)) !=
            PAM_SUCCESS)
            return retval;
    }

	But it never gets to 'pam_get_pass: top' ...

	The system is 4.6-STABLE, if that matters ... PgSQL 7.2.1 is
installed, and the build appears to work great ... only running appears to
fail.

	Testing is being done with the test.c that comes with pam_pgsql
itself, so that I don't throw any 'unknowns' into the mix ....
