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.

Reason:
The default version of PostgreSQL has been switched from 17 to 18.
The upgrade procedure can use up twice the space the databases
currently needs. If you have a big amount of stored data take a
closer look at the manpage of pg_upgrade for avoidance and/or
speedup of the upgrade.
The upgrade instructions consider a basic usage and do not match
complex scenarios like replication, sharding, or similar.
Upgrade instructions:
First stop your PostgreSQL, create PostgreSQL-binaries and backup your data.
If you have another Version of PostgreSQL installed, for example 17, your
files are named according to this.
# service postgresql stop
# pkg create postgresql17-server postgresql17-contrib
# mkdir /tmp/pg-upgrade
# tar xf postgresql17-server-17.9.pkg -C /tmp/pg-upgrade
# tar xf postgresql17-contrib-17.9.pkg -C /tmp/pg-upgrade
# pkg delete -f databases/postgresql17-server databases/postgresql17-contrib databases/postgresql17-client
Now update PostgreSQL:
pkg user:
# pkg install databases/postgresql18-server databases/postgresql18-contrib
# pkg upgrade
Portmaster users:
# portmaster databases/postgresql18-server databases/postgresql18-contrib
# portmaster -a
Portupgrade users:
# portinstall databases/postgresql18-server databases/postgresql18-contrib
# portupgrade -a
After installing the new PostgreSQL version you need to convert
all your databases to new version:
# su -l postgres -c "/usr/local/bin/initdb --encoding=utf-8 --lc-collate=C --no-data-checksums -D /var/db/postgres/data18 -U postgres"
# su -l postgres -c "pg_upgrade -b /tmp/pg-upgrade/usr/local/bin/ -d /var/db/postgres/data17/ -B /usr/local/bin/ -D /var/db/postgres/data18/ -U postgres "
Now the migration is finished. You can start PostgreSQL again with:
# service postgresql start
ATTENTION:
1) If you use non-default initdb options, you have to adjust the initdb-command accordingly
2) The initdb in the upgrade procedure uses '--no-data-checksums' to enable
pg_upgrade from before this change. You should review the documentation and
decide whether you want to then enable checksums with pg_checksums. Future
upgrade instructions for PostgreSQL 19 and later will assume a default
initdb, and therefore that checksums are enabled.
