Hi,
I'm debugging initdb using gdb.
I found that I could not step in the function getopt_long in
line 2572 in initdb.c.
I also found that the value of VAR optind never be changed.
VAR optind is always equal to 1 but how could optind be larger
than the value of argc(the value of argc is 6) in line 2648
and 2654.
I was so confused. Could someone give me some help? Thank you~
Why do you expect it to be? Perhaps if you tell us what problem
you're actually trying to solve we can help you better.
cheers

Hi, this is my story, it may be a little long :)
I mistook the parameter -W of initdb at the first time and used it
like this:
initdb -U pgsql -W 12345 -D /home/pgsql/pg_data
And I found the database was not created in the right directory, but
I could not find a log file to find out why.
So, I debug initdb and found out I have mistook the parameter -W, I
should use it like this:
initdb -U pgsql -W -D /home/pgsql/pg_data
This is arguably a bug. Maybe we should change this:
if (optind < argc)
{
pg_data = xstrdup(argv[optind]);
optind++;
}
to
if (optind < argc && strlen(pg_data) == 0)
{
pg_data = xstrdup(argv[optind]);
optind++;
}
i.e. we'd forbid:
initdb -D foo bar
which the OP's error more or less devolves to.
cheers
