docdb_query() modified so that it returns a data frame,
in which each column has just one type (atomic or list) across all the
rows of the respective column (previously, e.g. a mix of single-item
lists simplified to atomic values and of multi-item lists were
returned)docdb_create() and docdb_update() for
SQLite and PostgreSQL (only if on localhost) now import directly and
fast from ndjson files, in analogy to DuckDB (needs RSQLite

functionality across all databases (DuckDB, SQLite, PostgreSQL, MongoDB,
Elasticsearch, CouchDB); even though the API and unit tests remained,
user provisions may break e.g. to handle return values of databases that
previously were incompletely implemented (in particular Elasticsearch
and CouchDB). Details:

and is digested with a Javascript helperfields can now be nested fields (e.g.,
friends.name) to directly return values lifted from the
nested fieldlistfields parameter newly implemented to return dot
