who can help me?

Hi, all hackers,
I can startup database using command "/usr/local/pgsql/bin/postmaster -D /usr/local/pgsql/data".
But when I debug it using gdb and set args -D /usr/local/pgsql/data, it can't startup database. it says;
FATAL:  Database "postgres" does not exist in the system catalog.

Is there any difference between them?

Thanks a lot.

gdb doesn't like dealing with arguments (for me anyway).  Try setting
the data directory via the PGDATA environment variable.

I think postmaster checks what its name is (from argv[0]) and runs differently
depending on what it is. If there is an option to gdb to set arg 0, try using
it to set it to postmaster.

argv[0] gets set from what you use for a command, not what the actual
hard link name of the file is.
