arachne is a utility for scripting connected subgraphs. Databases frequently contain multiple independent data sets, especially in multi-tenant systems where client data are stored in the same tables but have no relation to each other. Extracting a single data set is more difficult the more complex the schema, and automated tools like pg_dump are all-or-nothing propositions. Given a database, a table to start from, and the value of a primary key in that table, arachne crawls the relationship graph to determine the dependency structure and exports the data in a safe order so no row is inserted before data it depends on. The output format is similar to that of pg_dump.
