Re: upgrading postgres

Hi,

Here are rough guide lines how to do this manually (FC2). Hope this helps.

( $ as postgres, # as root, paths may be different ):

Take a dump from your database(s):

$pg_dumpall -c > dump_file_for_8x

Shutdown postmaster:

Datadir out of the way:

#mv /usr/local/pgdata /usr/local/pgdata_old

Make new datadir:

#mkdir /usr/local/pgdata
#chown postgres /usr/local/pgdata

Previous install out of the way:

#mv /usr/local/pgsql /usr/local/pgsql_old

Extract your new Pg:

#gunzip postgresql-8x.tar.gz
#tar -xf postgresql-8x.tar

Configure, make and install, with --prefix=/path/ you can specify install
directory, ie. the -L swicth in initdb, default is /usr/local/pgsql/:

#cd postgresql-8x
#./configure --enable-locale --other-switches ...
#gmake
#gmake install

Initdb:

#chown -R postgres /usr/local/pgsql/
#su postgres
$/usr/local/pgsql/bin/initdb -D /usr/local/pgdata -L /usr/local/pgsql/share -E
LATIN1

(-D is your datadir, -L is where your postgres.bki resides and -E is the
default encoding)

You may also want to edit your postgresql.conf and pg_hba.conf files. For
locale and connections settings atleast perhaps.

Ok, let's start the server:

$/usr/local/pgsql/bin/postmaster -D /usr/share/pgdata -B 256 -N 128 &

-B is for buffers, -N is for number of connections, you might want to add -i
for outside connections (edit pg_hba.conf accordingly)

Finally, read your dump file in:

$psql -E template1 < dump_file_for_8x

Have fun and BR,

Aarni
