osm2pgsql-gen 2.0.0

NAME

osm2pgsql-gen - Generalize OpenStreetMap data - EXPERIMENTAL!

SYNOPSIS

osm2pgsql-gen [OPTIONS]…

DESCRIPTION

THIS PROGRAM IS EXPERIMENTAL AND MIGHT CHANGE WITHOUT NOTICE!

osm2pgsql-gen reads data imported by osm2pgsql from the database, performs various generalization steps specified by a Lua config file and writes the data back to the database. It is used in conjunction with and after osm2pgsql and reads the same config file.

This man page can only cover some of the basics and describe the command line options. See the Generalization chapter in the osm2pgsql Manual for more information.

OPTIONS

This program follows the usual GNU command line syntax, with long options starting with two dashes (--). Mandatory arguments to long options are mandatory for short options too.

MAIN OPTIONS

-a, --append: Run in append mode. The default is to run in create mode.
-S, --style=FILE: The Lua config file. Same as for osm2pgsql. Usually not required because it is read from the osm2pgsql_properties table.
-j, -jobs=NUM: Specifies the number of parallel threads used for certain operations. Setting this to the number of available CPU cores is a reasonable starting point. Minimum value and default is 1, maximum value is 256.

HELP/VERSION OPTIONS

-h, --help: Print help.
-V, --version: Print osm2pgsql version.

LOGGING OPTIONS

--log-level=LEVEL: Set log level (‘debug’, ‘info’ (default), ‘warn’, or ‘error’).
--log-sql: Enable logging of SQL commands for debugging.

DATABASE OPTIONS

-d, --database=NAME: The name of the PostgreSQL database to connect to. If this parameter contains an = sign or starts with a valid URI prefix (postgresql:// or postgres://), it is treated as a conninfo string. See the PostgreSQL manual for details.
-U, --username=NAME: Postgresql user name.
-W, --password: Force password prompt.
-H, --host=HOSTNAME: Database server hostname or unix domain socket location.
-P, --port=PORT: Database server port.
--schema=SCHEMA: Default for various schema settings throughout osm2pgsql-gen (default: public). The schema must exist in the database and be writable by the database user. It must be the same as used with osm2pgsql.
--middle-schema=SCHEMA: Database schema where the osm2pgsql_properties table is to be found. Default set with --schema. Set to the same value as on the osm2pgsql command line.
