nodbi 0.11.0

Potentially breaking changes

• 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)

Changes

• 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 >= 2.3.7.9014)
• Refactored docdb_update() for src_couchdb()
• Add message from docdb_create() if a data frame has column names with a dot(s) since dots in nodbi are used for JSON dot paths
• Add code to check database backend version requirements
• Adding info if PostgreSQL database is not yet created
• Factored out further code
