postgresql94-server - PostgreSQL is the most advanced open-source database available anywhere
||FreeBSD Ports Latest amd64
PostgreSQL is a sophisticated Object-Relational DBMS, supporting
almost all SQL constructs, including subselects, transactions, and
user-defined types and functions. It is the most advanced open-source
database available anywhere. Commercial Support is also available.
The original Postgres code was the effort of many graduate students,
undergraduate students, and staff programmers working under the direction of
Professor Michael Stonebraker at the University of California, Berkeley. In
1995, Andrew Yu and Jolly Chen took on the task of converting the DBMS query
language to SQL and created a new database system which came to known as
Postgres95. Many others contributed to the porting, testing, debugging and
enhancement of the Postgres95 code. As the code improved, and 1995 faded into
memory, PostgreSQL was born.
PostgreSQL development is presently being performed by a team of Internet
developers who are now responsible for all current and future development. The
development team coordinator is Marc G. Fournier (scrappy@PostgreSQL.ORG).
Support is available from the PostgreSQL developer/user community through the
support mailing list (questions@PostgreSQL.ORG).
PostgreSQL is free and the complete source is available.

For procedural languages and postgresql functions, please note that
you might have to update them when updating the server.
If you have many tables and many clients running, consider raising
kern.maxfiles using sysctl(8), or reconfigure your kernel
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 perform vacuum on all
databases nightly. Per default, it performs `vacuum analyze'. See the
script for instructions. For autovacuum settings, please review
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.d/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:
and run `cap_mkdb /etc/login.conf'.
Then add 'postgresql_class="postgres"' to /etc/rc.conf.
To initialize the database, run
You can then start PostgreSQL by running:
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
NB. If you're not using a checksumming filesystem like ZFS, you might
wish to enable data checksumming. It can only be enabled during
the initdb phase, by adding the "--data-checksums" flag to
the postgres_initdb_flags rcvar. Check the initdb(1) manpage
for more info and make sure you understand the performance
To run PostgreSQL at startup, add
'postgresql_enable="YES"' to /etc/rc.conf
