=========== BACKUP YOUR DATA! =============
As always, backup your data before
upgrading. If the upgrade leads to a higher
major revision (e.g. 9.6 -> 10), a dump
and restore of all databases is
required. This is *NOT* done by the port!
See https://www.postgresql.org/docs/current/upgrading.html

Message from python311-3.11.9:

Note that some standard Python modules are provided as separate ports
as they require additional dependencies. They are available as:
py311-gdbm databases/py-gdbm@py311
py311-sqlite3 databases/py-sqlite3@py311
py311-tkinter x11-toolkits/py-tkinter@py311
=====
Message from postgresql16-client-16.3:
--
The PostgreSQL port has a collection of "side orders":
postgresql-docs
For all of the html documentation
p5-Pg
A perl5 API for client access to PostgreSQL databases.
postgresql-tcltk
If you want tcl/tk client support.
postgresql-jdbc
For Java JDBC support.
postgresql-odbc
For client access from unix applications using ODBC as access
method. Not needed to access unix PostgreSQL servers from Win32
using ODBC. See below.
ruby-postgres, py-psycopg2
For client access to PostgreSQL databases using the ruby & python
languages.
postgresql-plperl, postgresql-pltcl & postgresql-plruby
For using perl5, tcl & ruby as procedural languages.
postgresql-contrib
Lots of contributed utilities, postgresql functions and
datatypes. There you find pg_standby, pgcrypto and many other cool
things.
etc...
=====
Message from postgresql16-server-16.3:
--
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, /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
~postgres/data/postgresql.conf.
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:
---
postgres:\
:lang=en_US.UTF-8:\
:setenv=LC_COLLATE=C:\
:tc=default:
---
and run `cap_mkdb /etc/login.conf'.
Then add 'postgresql_login_class="postgres"' to /etc/rc.conf, or
set it as the postgres 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 ~postgres/data/postgresql.conf
NB. FreeBSD's PostgreSQL port logs to syslog by default
See ~postgres/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 upgradring from a version 16.x < 16.3
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 /usr/local/share/postgresql/fix-CVE-2024-4317.sql
for each of your databases. For details, see
https://www.postgresql.org/support/security/CVE-2024-4317/
root@fbsd-test:~ # service postgresql initdb
Cannot 'initdb' postgresql. Set postgresql_enable to YES in /etc/rc.conf or use 'oneinitdb' instead of 'initdb'.
root@fbsd-test:~ # sysrc postgresql_enable="YES"
postgresql_enable: -> YES
root@fbsd-test:~ # service postgresql initdb
The files belonging to this database system will be owned by user "postgres".
This user must also own the server process.
The database cluster will be initialized with this locale configuration:
provider: libc
LC_COLLATE: C
LC_CTYPE: C.UTF-8
LC_MESSAGES: C.UTF-8
LC_MONETARY: C.UTF-8
LC_NUMERIC: C.UTF-8
LC_TIME: C.UTF-8
The default text search configuration will be set to "english".
Data page checksums are disabled.

initdb: warning: enabling "trust" authentication for local connections
initdb: hint: You can change this by editing pg_hba.conf or using the option -A, or --auth-local and --auth-host, the next time you run initdb.
Success. You can now start the database server using:
/usr/local/bin/pg_ctl -D /var/db/postgres/data16 -l logfile start
