I decided to upgrade my PostgreSQL server today. I did this upgrade slightly different than the last time. All commands were done as the root user unless indicated.

su -l pgsql
pg_dumpall | bzip2 -9c > all-db-9.2.10-2015-05-07.sql.bz2
chmod 0600 all-db-9.2.10-2015-05-07.sql.bz2
/usr/local/etc/rc.d/postgresql stop
make -C /usr/ports/databases/postgresql94-server config-recursive
portupgrade -fpvo databases/postgresql94-client  databases/postgresql92-client
portupgrade -fpvo databases/postgresql94-contrib databases/postgresql92-contrib
portupgrade -fpvo databases/postgresql94-server  databases/postgresql92-server
portupgrade -fprv -x databases/postgresql94-client -x databases/postgresql94-server -x databases/postgresql94-contrib databases/postgresql94-client
mv /usr/local/pgsql/data /usr/local/pgsql/data0
su -l pgsql -c 'mkdir /usr/local/pgsql/data'
/usr/local/etc/rc.d/postgresql initdb
/usr/local/etc/rc.d/postgresql start
su -l pgsql
bzcat all-db-9.2.10-2015-05-07.sql.bz2 | psql -f - template1
# Transfer all relevant settings from /usr/local/pgsql/data0 to /usr/local/pgsql/data for pg_hba.conf and postgresql.conf
/usr/local/etc/rc.d/postgresql restart
su -l pgsql
pg_dumpall | bzip2 -9c > all-db-9.4.1-2015-05-07.sql.bz2
chmod 0600 all-db-9.4.1-2015-05-07.sql.bz2
rm -R /usr/local/pgsql/data0
