ogr2ogr:tldr:f6382
The command ogr2ogr is used to convert data between different spatial formats. In this case, it is being used to convert a GeoPackage file (.gpkg) to a PostgreSQL database.
The -f flag specifies the output format, in this case PostgreSQL.
The PG:dbname="${database_name}" part of the command specifies the connection details for the PostgreSQL database. ${database_name} is a placeholder that should be replaced with the actual name of the database you want to connect to. It is typically provided as an environment variable or as a parameter when running the command.
${path-to-input}.gpkg specifies the path to the input GeoPackage file that you want to convert. The ${path-to-input} portion is also a placeholder that should be replaced with the actual file path.
