OSM2PGSQL-REPLICATION(1) OSM2PGSQL-REPLICATION(1) NAME osm2pgsql-replication - osm2pgsql database updater SYNOPSIS osm2pgsql-replication [-h] {init,update,status} ... DESCRIPTION Update an osm2pgsql database with changes from an OSM replication server. This tool initialises the updating process by looking at the import file or the newest object in the database. The state is then saved in a table in the database. Subsequent runs download newly available data and apply it to the database. See the help of the 'init' and 'update' command for more information on how to use osm2pgsql-replication. AVAILABLE COMMANDS osm2pgsql-replication init Initialise the replication process. osm2pgsql-replication update Download newly available data and apply it to the database. osm2pgsql-replication status Print information about the current replication status, option- ally as JSON. COMMAND 'osm2pgsql-replication init' usage: osm2pgsql-replication init [-h] [-q] [-v] [-d DB] [-U NAME] [-H HOST] [-P PORT] [-p PREFIX] [--middle-schema SCHEMA] [--schema SCHEMA] [--osm-file FILE | --server URL] [--start-at TIME] Initialise the replication process. This function sets the replication service to use and determines from which date to apply updates. You must call this function at least once to set up the replication process. It can safely be called again later to change the replication servers or to roll back the update process and reapply updates. There are different methods available for initialisation. When no addi- tional parameters are given, the data is initialised from the data in the database. If the data was imported from a file with replication in- formation and the properties table is available (for osm2pgsql >= 1.9) then the replication from the file is used. Otherwise the minutely up- date service from openstreetmap.org is used as the default replication service. The start date is either taken from the database timestamp (for osm2pgsql >= 1.9) or determined from the newest way in the data- base by querying the OSM API about its creation date. The replication service can be changed with the '--server' parameter. To use a different start date, add '--start-at' with an absolute ISO timestamp (e.g. 2007-08-20T12:21:53Z). When the program determines the start date from the database timestamp or way creation date, then it subtracts another 3 hours by default to ensure that all new changes are available. To change this rollback period, use '--start-at' with the number of minutes to rollback. This rollback mode can also be used to force initialisation to use the database date and ignore the date from the replication information in the file. The initialisation process can also use replication information from an OSM file directly and ignore all other date information. Use the com- mand 'osm2pgsql-replication --osm-file <filename>' for this. DEFAULT ARGUMENTS 'osm2pgsql-replication init' -q, --quiet Print only error messages -v, --verbose Increase verboseness of output DATABASE ARGUMENTS 'osm2pgsql-replication init' The following arguments can be used to set the connection parameters to the osm2pgsql database. You may also use libpq environment variables to set connection parameters, see https://www.postgresql.org/docs/cur- rent/libpq-envars.html. If your database connection requires a pass- word, use a pgpass file, see https://www.postgresql.org/docs/cur- rent/libpq-pgpass.html. -d DB, --database DB Name of PostgreSQL database to connect to or conninfo string -U NAME, --username NAME, --user NAME PostgreSQL user name -H HOST, --host HOST Database server host name or socket location -P PORT, --port PORT Database server port -p PREFIX, --prefix PREFIX Prefix for table names (default 'planet_osm') --middle-schema SCHEMA Name of the schema to store the table for the replication state in --schema SCHEMA Name of the schema for the database REPLICATION SOURCE ARGUMENTS 'osm2pgsql-replication init' --osm-file FILE Get replication information from the given file. --server URL Use replication server at the given URL --start-at TIME Time when to start replication. When an absolute timestamp (in ISO format) is given, it will be used. If a number is given, then replication starts the number of minutes before the known date of the database. COMMAND 'osm2pgsql-replication update' usage: osm2pgsql-replication update update [options] [-- param [param ...]] Download newly available data and apply it to the database. The data is downloaded in chunks of '--max-diff-size' MB. Each chunk is saved in a temporary file and imported with osm2pgsql from there. The temporary file is normally deleted afterwards unless you state an ex- plicit location with '--diff-file'. Once the database is up to date with the replication source, the update process exits with 0. Any additional arguments to osm2pgsql need to be given after '--'. Database and the prefix parameter are handed through to osm2pgsql. They do not need to be repeated. '--append' and '--slim' will always be added as well. Use the '--post-processing' parameter to execute a script after osm2pgsql has run successfully. If the updates consists of multiple runs because the maximum size of downloaded data was reached, then the script is executed each time that osm2pgsql has run. When the post-pro- cessing fails, then the entire update run is considered a failure and the replication information is not updated. That means that when 'up- date' is run the next time it will recommence with downloading the diffs again and reapplying them to the database. This is usually safe. The script receives two parameters: the sequence ID and timestamp of the last successful run. The timestamp may be missing in the rare case that the replication service stops responding after the updates have been downloaded. param Extra parameters to hand in to osm2pgsql. OPTIONS 'osm2pgsql-replication update' --diff-file FILE File to save changes before they are applied to osm2pgsql. --max-diff-size MAX_DIFF_SIZE Maximum data to load in MB (default: 500MB) --osm2pgsql-cmd OSM2PGSQL_CMD Path to osm2pgsql command --once Run updates only once, even when more data is available. --post-processing SCRIPT Post-processing script to run after each execution of osm2pgsql.
