Hi Howard,
Here's a rough guide line how to move or upgrade your db.
Just did this once again. (From FC2 / 8.0.1 to CentOs 4.4 / 8.1.5)
----
Take a dump from your db:
$pg_dumpall -c > dump_file_for_new
If you're upgrading on the same machine:
Shutdown postmaster:
Datadir out of the way:
#mv /usr/share/pgdata /usr/share/pgdata_old
New datadir:
#mkdir /usr/share/pgdata
#chown postgres /usr/share/pgdata
Previous install out of the way:
#mv /usr/share/pgsql /usr/share/pgsql_old
New istall:
Extract your new Pg:
#gunzip postgresql-8.x.tar.gz
#tar -xf postgresql-8.x.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-8.x
#./configure --with...
#gmake or make
#gmake install or make install
Initdb:
#chown -R postgres /usr/local/pgsql/
#su postgres
$/usr/local/pgsql/bin/initdb -D /usr/share/pgdata -L /usr/local/pgsql/share -E
ENCODING
Edit & save .conf files
Start the server:
$/usr/local/pgsql/bin/postmaster -D /usr/share/pgdata -B no. of buffers -N no.
of connections &
You might want to add -i for outside connections (edit pg_hba.conf
accordingly)
Read your dump file in:
$psql -E template1 < dump_file_for_new
