Problem upgrading PGSQL7.3.2 from PGSQL6.5 under RHLinux6.5 - missing global/pg_control

Hi all

Been trying to get postmaster to run after a PGSQL upgrade from 6.5
to 7.3.2. (I know, it's a big step!) Below is the transcription of the
steps
I've taken so far to give the complete details. I'm installing under
/usr/local/pgsql_7.3.2
and my database data dir is on another physical drive under
/mnt/huge/postgresql.
(It's gotta be here since I don't have room on the other drive).

The short version is that everything is fine up until the postmaster phase.
It's really weird. Firstly, when trying to start postmaser, the PG_VERSION
file did not exist (I created it later, but shouldn't the "gmake install" or
even
the "initdb" have done this already?) Anyway, I create this file using

"echo "7.3.2" > PG_VERSION

and continue on. Then, after I create the file, it says it can't find the
global/pg_control
file under my data directory "/mnt/huge/postgresql". I haven't seen this
structure
before in the old installation, so I'm stumped. (Again, shouldn't the
creation of these
directories and files be handled by "gmake install" or "initdb"?) I ran
"gmake check"
and it found no errors. And running postmaster in higher debug mode just
gave this:

DEBUG: proc_exit(2)
DEBUG: shmem_exit(2)
DEBUG: exit(2)

Anyway, below are the details. Hope you can help since I'd really like to
get
this running soon and continue development... :)

Take care,
Jason

*** AS ROOT ***

- backup the data using pg_dumpall
- shut down postmaster

*many pgsql binaries and dirs scattered around in the default RH
installation,
so rename them to ensure no versioning conflicts

- renamed /var/lib/pgsql to /var/lib/old_pgsql
- renamed /usr/data to /usr/old_data
- renamed the following old binaries in /usr/bin

# chown postgres /mnt/huge/postgresql
# su - postgres
$ ./bin/initdb -D /mnt/huge/postgresql

FATAL: data directory /mnt/huge/postgresql has group or world access;
permissions should be u=rwx (0700)

$ ### OK, give it the permissions it requires.
$ chmod 0700 /mnt/huge/postgresql
$ ./bin/initdb -D /mnt/huge/postgresql

The files belonging to this database system will be owned by user
"postgres".
This user must also own the server process.

The database cluster will be initialized with locale en_US.
This locale setting will prevent the use of indexes for pattern matching
operations. If that is a concern, rerun initdb with the collation order
set to "C". For more information see the Administrator's Guide.

initdb: The directory /mnt/huge/postgresql/ exists but is not empty.
If you want to create a new database system, either remove or empty
the directory /mnt/huge/postgresql/ or run initdb with
an argument other than /mnt/huge/postgresql/.

$ ./postmaster -D /mnt/huge/postgresql
FATAL: File /mnt/huge/postgresql/PG_VERSION is missing. This is not a valid
data directory.

$ #### Is this normal? Where is the PG_VERSION file? Ok, so create it.
$ echo "7.3.2" > /mnt/huge/postgresql/PG_VERSION

$ ./postmaster -D /mnt/huge/postgresql
./postmaster does not find the database system.
Expected to find it in the PGDATA directory "/mnt/huge/postgresql",
but unable to open file "/mnt/huge/postgresql/global/pg_control": No such
file or directory

$ ### If this is needed, shouldn't have initdb created it? :(
$ ### try the tests via gmake check
$ gmake check

All 89 tests passed.
