pgloader

Unlike PostgreSQL's default transactional COPY, pgloader continues processing valid data and isolates rejected entries, preventing entire migrations from failing due to minor errors, as emphasized in the README.

Handles common incompatibilities like converting MySQL's invalid zero-dates to PostgreSQL NULL values, simplifying migrations from sources such as MySQL without manual cleanup.

Transfers not only data but also table definitions, indexes, foreign keys, and comments in a single command, reducing manual effort during database transitions.

Improves load times by loading data in parallel when migrating from databases like MySQL, enhancing efficiency for large datasets as noted in the features.
