Another PGINDENT run that changes variable indenting and case label indenting.  Also static variable indenting.

Subject: [HACKERS] password authentication

This patch adds support for plaintext password authentication.  To use
it, you add a line like

host         all         0.0.0.0       0.0.0.0           password  pg_pwd.conf


to your pg_hba.conf, where 'pg_pwd.conf' is the name of a file containing
the usernames and password hashes in the format of the first two fields
of a Unix /etc/passwd file.  (Of course, you can use a specific database
name or IP instead.)

Then, to connect with a password through libpq, you use the PQconnectdb()
function, specifying the "password=" tag in the connect string and also
adding the tag "authtype=password".

I also added a command-line switch '-u' to psql that tells it to prompt
for a username and password and use password authentication.

another one in Solaris' port-protos.h.

The following patch will bring inet_aton's prototype into scope for
Ultrix to silence a compilation warning.

If the intention is to have inet_aton's prototype in its own header
filer, the declaration in Solaris' port-protos.h should be removed.
If the declaration in port-protos.h is deemed to be the correct
place, a declaration should be added in Ultrix' port-protos.h

At least the first two should be fixed before the final release of 6.0.

1)      There is a mismatch between the type declared in the catalog for
        the input/output attributes of pg_type and the actual type of
        values stored in the table.  The type of typinput, typoutput,
        typsend and typreceive are declared oid (26) while the values are
        regproc (24).  The error was there also in previous versions but
        nobody noticed it until an Assert has been added in ExecEvalVar.
        The effect is that it is now impossible to replace the typoutput
        of existing data types with new procs.

2)      The identd hba fails after the first time because the data read
        from the identd socket is not zero-terminated and strlen reports
        an incorrect length if the stack contains garbage, which usually
        happens after the first connection has been made.

3)      The new initdb wants to create itself the data directory. This
        implies that the parent directory must be writable by postgres and
        this may not always be desirable.  A better solution would be to
        allow the directory to be created by root and then filled by initdb.
        It would also nice to have some reasonable default for PGLIB and
        PGDATA like the previous version did.  This applies also to the
        postmaster executable.

For sparc_solaris, add inet_aton prototype, since it isn't in the header
files included for the standard C library functions.
