PostgreSQL

# cd /usr/local/src
# tar -zxvf postgresql-x.x.x.tar.gz
# cd postgresql-x.x.x
# ./configure
# make
# make install

PostgreSQL installed, let the initial settings:

# useradd postgres
# passwd postgres
# mkdir /usr/local/pgsql/data
# chown postgres /usr/local/pgsql/data
# su postgres

User and server folder created, we initialize the first time the server

#initdb -D /usr/local/pgsql/data

.
..
...
....
PATH=$PATH:/usr/local/pgsql/bin
MANPATH=$MANPATH:/usr/local/pgsql/man
export PATH MANPATH

and :

# cd /usr/local/src/postgresql-x.x.x/contrib/start-scripts/
# cp linux /etc/rc.d/rc.postgresql
# chmod a+x /etc/rc.d/rc.postgresql
