RE: 7.0.2 -> 7.0.3 problem

You have to dump/initdb/reload if you change the block size. Simply
recompiling is not going to work.

Subject: [HACKERS] 7.0.2 -> 7.0.3 problem

I just upgraded to 7.0.3 and tried to start the backend like

/usr/local/pgsql/bin/postmaster -B 256 -o '-S 10240 -s' -D
/usr/local/pgsql/data -i > /usr/local/pgsql/postgres.log 2>&1 &

.. as I've done with 7.0.2, it failed to start and got this in my
postgresql.log :

DEBUG: Data Base System is starting up at Sun Nov 12 18:20:04 2000
FATAL 2: Read("/usr/local/pgsql/data/pg_control") failed: 2
FATAL 2: Read("/usr/local/pgsql/data/pg_control") failed: 2
Startup failed - abort

The only compilation change I made was to increase BLCKSZ to 32k (which
has
been running in a production 7.0.2 environment for quite some time).

So what's up? Just to make sure I made the permissions 777 all the way
down
to pg_control but it had no effect.

Hmm, I just re-installed 7.0.2 and I get the same error with it -- not
good.

My development server, which is virtually the same, did fine when I
installed 7.0.3 so I'm guessing it's not a problem across the board..

I also notice in the log that it's
Read("/usr/local/pgsql/data/pg_control")
that's failing and when I move pg_control out of the way, it's Open()
that
fails..

I did nothing but stop the postmaster, compile and install 7.0.3 and
start
the postmaster. then compiled and installed 7.0.2 again and all of the
sudden the 7.0.2 or 7.0.3 backend doesn't start -- it makes no sense.

As always, any help is appreciated. Thanks!
