pveriexport

pveriexport is a command-line utility designed for exporting data from a PostgreSQL database. It allows users to extract table contents or query results into various file formats, facilitating data migration, backup, or analysis. The tool focuses on providing a straightforward way to get data out of PostgreSQL without requiring complex scripting or the use of more comprehensive database administration tools.

The primary function of pveriexport is to select specific data and direct it to an output file. This can include the entire content of a table, a subset of rows based on a WHERE clause, or the results of an arbitrary SQL query. Users typically specify the connection details for the PostgreSQL database, the data to be exported (e.g., table name or SQL query), and the desired output format.

Common output formats supported by pveriexport include CSV (Comma Separated Values), TSV (Tab Separated Values), and plain text. These formats are widely compatible with other software and systems, making the exported data easily importable into spreadsheets, other databases, or data analysis tools. The utility often provides options for handling data types, encoding, and delimiters, allowing for customization of the exported file.

pveriexport is particularly useful for automated data extraction tasks or when a quick and simple export is needed. Its command-line interface makes it suitable for inclusion in shell scripts and scheduled jobs, enabling regular data dumps or feeding data into other automated processes. While not as feature-rich as tools like `pg_dump` for full database backups, pveriexport serves a specific niche for targeted data exports.
