[ { type: install 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, /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 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 /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/ EOM } ]
