You can use OpenStreetMaps on your own hardware. You need to grab map files first, which can be found at https://download.geofabrik.de. Once you downloaded it, install PostgreSQL and enable few extensions: It may be useful at some point later on especially if you would like to try build your own tile server. Next you need to install osm2pgsql and it can be found in system packages in Ubuntu 22. Then: Now give it database password and it will start loading. Depening on hardware it might take from few minutes to tens of hours in case of large files like Europe
Starting from PostgreSQL 10 we have available new type of paritioning, which is declarative one. Before we had inheritance which is also good but has some limitations. Now, with declarative partitioning user need not to specify partition name while inserting data. To create partitioned table: There are few things worth explaining. First one is BIGSERIAL data type. It is a bigger form of integer type with automatic sequence creation, which is very convenient. Second thing is PARTITION BY RANGE(columnname). It defined that the data will be spread across paritions based on created_at date range. It positively affects query performance. To
In case you would like to enable some PostgreSQL extensions there is basically one thing you should do which is install postgresql14-contrib package and then fire CREATE EXTENSION from PostgreSQL itself.
Latest Clustercontrol – version 1.9.4 – installation somehow requires pg_stat_statements to be activated in PostgreSQL 14. I have never noticed it before, both on 9.6, 12 and 14. This is simple fix. Change postgresql.conf configuration file (which should be either in /etc or /var/lib/ in standard package installations): Then activate extension in psql: Restart server and you are done.
PostgreSQL 14 has few improvements over previous versions, especially older ones, like 9.6. This includes automatic data direction using partitioning. So, let’s install it on CentOS 7. Then you should login to the database and set password: Basic configuration includes firewall setup (if it’s active), access control and performance settings: I strongly recommend visiting pgtune.leopard.in.ua for tuning parameters. Last thing is to set interface address on which server will be listening, it’s set in: Now you are good to go.
