PostgreSQL 11, the latest version of the world’s most advanced open source database. PostgreSQL 11 provides users with improvements to overall performance of the database system, with specific enhancements associated with very large databases and high computational workloads. Further, PostgreSQL 11 makes significant improvements to the table partitioning system, adds support for stored procedures capable of transaction management, improves query parallelism and adds parallelized data definition capabilities, and introduces just-in-time (JIT) compilation for accelerating the execution of expressions in queries. "For PostgreSQL 11, our development community focused on adding features that improve PostgreSQL's ability to manage very large databases," said Bruce Momjian, a core team member of the PostgreSQL Global Development Group. "On top of PostgreSQL's proven performance for transactional workloads, PostgreSQL 11 makes it even easier for developers to run big data applications at scale." PostgreSQL benefits from over 20 years of open source development and has become the preferred open source relational database for developers. The project continues to receive recognition across the industry, and has been featured as the "DBMS of the Year 2017" by DB-Engines and in the SD Times 2018 100. PostgreSQL 11 is the first major release since PostgreSQL 10 was released on October 5, 2017. The next update release for PostgreSQL 11 containing bug fixes will be PostgreSQL 11.1, and the next major release with new features will be PostgreSQL 12.

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
|
|
appropriately.
|
|
|
|
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, %%PREFIX%%/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
|
|
~pgsql/data/postgresql.conf.
|
|
|
|
If you plan to access your PostgreSQL server using ODBC, please
|
|
consider running the SQL script %%PREFIX%%/share/postgresql/odbc.sql
|
|
to get the functions required for ODBC compliance.
|
|
|
|
Please note that if you use the rc script,
|
|
%%PREFIX%%/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:
|
|
---
|
|
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
|
|
|
|
%%PREFIX%%/etc/rc.d/postgresql initdb
|
|
|
|
You can then start PostgreSQL by running:
|
|
|
|
%%PREFIX%%/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
|
|
|
|
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
|
|
implications.
|
|
|
|
======================================================================
|
|
|
|
To run PostgreSQL at startup, add
|
|
'postgresql_enable="YES"' to /etc/rc.conf
|
