PostgreSQL 10.5 を FreeBSD 12.0-RELEASE に入れる2019年10月31日 13時18分44秒

FreeBSD で別のデータベースを試したく、PostgreSQL を入れてみた。FreeBSD 12.1-RELEASE が間近で、12.1-RELEASE 用の pkg を見るとこれよりも新しいバージョンもあるが、基本的な機能の実験が目的なので、少し古いものをインストールした。

まずは、pkg で確認。

# pkg search '^postgresql.*server'
postgresql10-server-10.5       PostgreSQL is the most advanced open-source datab
ase available anywhere

この中では最新を選んで pkg install。
# pkg install postgresql10-server

  =========== BACKUP YOUR DATA! =============
  As always, backup your data before
  upgrading. If the upgrade leads to a higher
  minor revision (e.g. 8.3.x -> 8.4), a dump
  and restore of all databases is
  required. This is *NOT* done by the port!

Message from postgresql10-client-10.5:

The PostgreSQL port has a collection of "side orders":
  For all of the html documentation

  A perl5 API for client access to PostgreSQL databases.

  If you want tcl/tk client support.

  For Java JDBC support.

  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

postgresql-plperl, postgresql-pltcl & postgresql-plruby
  For using perl5, tcl & ruby as procedural languages.

  Lots of contributed utilities, postgresql functions and
  datatypes. There you find pg_standby, pgcrypto and many other cool

Message from postgresql10-server-10.5:

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

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

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:
and run `cap_mkdb /etc/login.conf'.
Then add 'postgresql_class="postgres"' to /etc/rc.conf.


To initialize the database, run

  /usr/local/etc/rc.d/postgresql initdb

You can then start PostgreSQL by running:

  /usr/local/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


To run PostgreSQL at startup, add
'postgresql_enable="YES"' to /etc/rc.conf

/etc/rc.conf を更新。

# echo 'postgresql_enable="YES"' >> /etc/rc.conf
# /usr/local/etc/rc.d/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 locale "C".
The default text search configuration will be set to "english".

Data page checksums are disabled.

WARNING: enabling "trust" authentication for local connections
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/data10 -l logfile start
