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 (https://osm2pgsql.org/doc/manual.html#generalization) 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.
