Thread: 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

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

See the above.  Most of the rest of this is due to the fact that initdb
didn't run. The --datadir isn't the database structure directory.

You failed to run initdb.  Note the complaint:

This is a safety precaution to keep people from initdb'ing over an
existing installation ...
