TimescaleDB-1 安装
前置条件：
1、操作系统ubuntu2204
2、已经通过apt的方式安装了pg14
当然其他的操作系统，官方文档中也有说明。
一、安装
https://docs.timescale.com/self-hosted/latest/install/installation-linux/
Installing self-hosted TimescaleDB on Debian-based systems
# 1、安装相关仓库
apt install gnupg postgresql-common apt-transport-https lsb-release wget
# 2、运行仓库安装脚本
/usr/share/postgresql-common/pgdg/apt.postgresql.org.sh
# 3、安装TimescaleDB 第三方仓库
echo "deb https://packagecloud.io/timescale/timescaledb/ubuntu/ $(lsb_release -c -s) main" | sudo tee /etc/apt/sources.list.d/timescaledb.list# 4、安装TimescaleDB GPG key（Ubuntu21.10以后）
wget --quiet -O - https://packagecloud.io/timescale/timescaledb/gpgkey | sudo gpg --dearmor -o /etc/apt/trusted.gpg.d/timescaledb.gpg# 5、更新仓库
apt update# 6、安装TimescaleDB
apt install timescaledb-2-postgresql-14# 7、Configure your database by running the timescaledb-tune script, which is included with the timescaledb-tools package. Run the timescaledb-tune script using the sudo timescaledb-tune command. For more information, see the configuration section.
这一段没看懂，我也啥也没做，不过后面的步骤就报错了
最后解决问题的方法也很简单：
修改postgresql配置文件：
root@odoo-pc:~# vi /etc/postgresql/14/main/postgresql.conf
在文件底部增加一行
shared_preload_libraries = 'timescaledb'保存文件，重启postgresql
root@odoo-pc:~# systemctl restart postgresqlSet up the TimescaleDB extension
# 升级psql
apt-get update
apt-get install postgresql-client
安装TimeScaleDB
# 修改postgres密码
sudo -u postgres psql
\password postgres
\q
psql -U postgres -h localhost
# 创建时序数据库
CREATE database tsdb;
# 连接到tsdb
\c tsdb
# 增加TimescaleDB扩展
CREATE EXTENSION IF NOT EXISTS timescaledb;
# 看看是否安装成功
