Description:
Tools for exporting 'PostgreSQL' tables to 'Parquet' files, with support for chunked writes, column type overrides, and timezone-aware timestamp handling. Includes functions for maintaining a local 'Parquet' data library sourced from 'WRDS' (Wharton Research Data Services), with update-checking based on table metadata, and archive management utilities for versioning local data files. See Gow and Ding (2024) "Empirical Research in Accounting: Tools and Methods" <doi:10.1201/9781003456230>.
