PostgreSQL
=========== BACKUP YOUR DATA! ============= As always, backup your data before upgrading. If the upgrade leads to a higher minor revision (e.g. 7.3.x -> 7.4), a dump and restore of all databases is required. This is *NOT* done by the port!
Press ctrl-C *now* if you need to pg_dump. ===========================================
cd /usr/ports/databases/postgresql82-server/
make; make install
this will instal both the server and client ports
The port is set up to use autovacuum for new databases, but you might
also want to vacuum and perhaps backup your database regularly. There
is a periodic script, /usr/local/etc/periodic/daily/502.pgsql, that
you may find useful. You can use it to backup and perfom vacuum on all
databases nightly. Per default, it perfoms `vacuum analyze'. See the
script for instructions. For autovacuum settings, please review
~pgsql/data/postgresql.conf.
To allow many simultaneous connections to your PostgreSQL server, you
should raise the SystemV shared memory limits in your kernel. Here are
example values for allowing up to 180 clients (configurations in
postgresql.conf also needed, of course):
options SYSVSHM
options SYSVSEM
options SYSVMSG
options SHMMAXPGS=65536
options SEMMNI=40
options SEMMNS=240
options SEMUME=40
options SEMMNU=120
If you plan to access your PostgreSQL server using ODBC, please
consider running the SQL script /usr/local/share/postgresql/odbc.sql
to get the functions required for ODBC compliance.
Please note that if you use the rc script,
/usr/local/etc/rc.conf/postgresql, to initialize the database, unicode (UTF-8) will be used to store character data by default. Set postgresql_initdb_flags or use login.conf settings described below to alter this behaviour. See the start rc script for more info.
To set limits, environment stuff like locale and collation and other
things, you can set up a class in /etc/login.conf before initializing
the database. Add something similar to this to /etc/login.conf:
postgres:\
:lang=en_US.UTF-8:\
:setenv=LC_COLLATE=C:\
:tc=default:
and run `cap_mkdb /etc/login.conf'.
Then add 'postgresql_class="postgres"' to /etc/rc.conf.
To initialize the database, run
/usr/local/etc/rc.d/postgresql initdb
You can then start PostgreSQL by running:
/usr/local/etc/rc.d/postgresql start
For postmaster settings, see ~pgsql/data/postgresql.conf
NB. FreeBSD's PostgreSQL port logs to syslog by default
See ~pgsql/data/postgresql.conf for more info
To run PostgreSQL at startup, add
'postgresql_enable="YES"' to /etc/rc.conf

===> SECURITY REPORT:
This port has installed the following files, which may act as network
servers and may therefore pose a remote security risk to the system.
/usr/local/bin/postgres
This port has installed the following startup scripts, which may cause
these network services to be started at boot time.
/usr/local/etc/rc.d/postgresql
If there are vulnerabilities in these programs there may be a security
risk to the system. FreeBSD makes no guarantee about the security of
ports included in the Ports Collection. Please type 'make deinstall'
to deinstall the port if this is a concern.
For more information, and contact details about the security
status of this software, see the following webpage:
- Run /usr/local/etc/rc.d/postgresql initdb to initialize the DB
- vi /usr/local/pgsql/data/pg_hba.conf and add the following
