message: <<EOM
|
|
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
|
|
~%%PG_USER%%/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:
|
|
---
|
|
%%PG_USER%%:\
|
|
:lang=en_US.UTF-8:\
|
|
:setenv=LC_COLLATE=C:\
|
|
:tc=default:
|
|
---
|
|
and run `cap_mkdb /etc/login.conf'.
|
|
Then add 'postgresql_login_class="%%PG_USER%%"' to /etc/rc.conf, or
|
|
set it as the %%PG_USER%% user's login class in /etc/passwd.
|
|
|
|
======================================================================
|
|
|
|
To use PostgreSQL, enable it in rc.conf using
|
|
|
|
sysrc postgresql_enable=yes
|
|
|
|
To initialize the database, run
|
|
|
|
service postgresql initdb
|
|
|
|
You can then start PostgreSQL by running:
|
|
|
|
service postgresql start
|
|
|
|
For postmaster settings, see ~%%PG_USER%%/data/postgresql.conf
|
|
|
|
NB. FreeBSD's PostgreSQL port logs to syslog by default
|
|
See ~%%PG_USER%%/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 be enabled during
|
|
the initdb phase, by adding the "--data-checksums" flag to
|
|
the postgresql_initdb_flags rcvar. Otherwise you can enable it later by
|
|
using pg_checksums. Check the initdb(1) manpage for more info
|
|
and make sure you understand the performance implications.
|
|
|

SECURITY ADVICE
|
|
|
|
If upgrading from a version 15.x < 15.7:
|
|
A security vulnerability was found in the system views pg_stats_ext
|
|
and pg_stats_ext_exprs, potentially allowing authenticated database
|
|
users to see data they shouldn't. If this is of concern in your
|
|
installation, run the SQL script %%DATADIR%%/fix-CVE-2024-4317.sql
|
|
for each of your databases. For details, see
|
|
https://www.postgresql.org/support/security/CVE-2024-4317/
