Thread: Upgrading from 7.4 to 8.2

Hi!
I have PostgreSQL 7.4 DBM and want to upgrade to 8.2 (latest in version 8 I quess).

Can use the DATADIR from 7.4 and just upgrade the DBM/postgresql server to 8.2?

Is the upgrade from 7 to 8 procedure written down somewhere? (could not find anyting at
http://www.postgresql.org/docs/techdocs.2,except from 6 to 7) 

I guess I could dump all my data and restore it later but it would be much nicer if it was possible to just start a new
PostgreSQLserver with the old DATADIR repository! 

Thanks!

/Rick

Hi Rickard!

As far as i know you will have to dump and restore the databases for the
upgrade since a lot of internals have been changed from 7.4 to 8.2.
A description on how to upgrade can be found here:
http://www.postgresql.org/docs/8.2/interactive/install-upgrading.html
And here: http://www.postgresql.org/docs/8.2/interactive/migration.html

Good luck!

Greetings,
Matthias

Dear Rickard,

The jump from 7.4 to 8.2 is rather big.
I would suggest doing just a dry run by  dumping
the database schema without data and restoring it
into 8.2 database . this can be time saving in detecting
possible problems in migration.

in case there is some non trivial problem
you may take intermediate path of upgrading
7.4-->8.0.x-->8.1.x -->8.2.0
where x denotes the last minor release of a major
release.

regds
mallah.

Hi!
Thanks for your replies!

My problem is that I want to move the DBM to a different machine so now when it doesn't seem to be any easy/trivial way
tomigrate from 7.4 to 8.2 I might consider to continue with 7.4. 

If I decide to continue with 7.4 I guess the procedure to move the DATADIR to the new machine and then start the
postgresqlserver there with the old DATADIR should work without problems? 

Thanks, again!

It was not my intention to scare you. Please do not misread.
It is always recommended to run the latest version of pgsql
unless you really have to stick to an older version.
Release notes shall tell you about the new features that
you get in various versions. Newer versions almost always have better
planner and numerous performance improvements.

Yes that is rite.

Very easy,

Install the new version of PostgreSQL on your new machine.  Then use the new machine's install to pg_dump the old machine's database and load it into the new machine (obviously, the machines must be table to talk to each other over the network).  Very easy.  That is how I upgraded all of my servers from 7.3.4 to 8.1.3. (An upgrade that went very smoothly with no hiccups.)

Except that there are behavioral differences between 8.1.3 and 7.4
including how floats respond to '' input. I believe there are also
library version bumps which will likely effect him if he does not
recompile his apps because he might remove 7.4 after getting a
successful upgrade of his data just to find that PHP or Perl doesn't
work anymore.

Hi!
I'm tying to compile postgresql 8.2.0 under:
SunOS 5.8 Generic_117350-36 sun4u sparc SUNW,Sun-Blade-100

and got problems while compiling, the problem seems to be that gcc (or configure) adds my username (sjostric) to the
gcccommand line. Like this: 

gcc -O2 -Wall -Wmissing-prototypes -Wpointer-arith -Winline -Wdeclaration-after-statement -Wendif-labels
-fno-strict-aliasingsjostric -I../../src/port -DFRONTEND -I../../src/include   -c -o isinf.o isinf.c 

which results in that I get:
gcc: sjostric: No such file or directory

My configure command line is:
/configure --prefix=/home/sjostric/postgresql/8.2.0 --exec-prefix=/home/sjostric/postgresql/8.2.0 --without-readline

Any ideas?

Thanks!

The new machine will need to have the same architecture and Postgres will
need to have been built with the same way for each machine. Some of the
configure options affect the format of how data is stored. Different
compilers or compiler options could also change how data is stored.
