Teradata to PostgreSQL Integration

How Datrise loads Teradata into PostgreSQL

Datrise syncs Teradata's tables, rows, schemas, indexes, primary indexes, and query history into PostgreSQL as a typed table per source entity. Flexible or custom fields land in jsonb columns, and timestamps such as created, updated, and status changes are typed as timestamptz.

Sync is incremental: Datrise uses a watermark on each entity's updated-at, applied with INSERT … ON CONFLICT DO UPDATE, so re-runs update only what changed. Optional declarative range partitioning by load date for high-volume tables. PostgreSQL folds unquoted identifiers to lowercase, so Datrise normalizes mixed-case source fields to snake_case.

Ideal for operational analytics and application backends that need fresh, queryable copies of your data.

Endpoints

Teradata: Teradata analytical database for enterprise workloads.

PostgreSQL: Open-source relational database with strong SQL and extensions.

How Teradata entities map to PostgreSQL

Teradata entity	PostgreSQL object	Notes
tables	`teradata_d_tables`	id PK · custom fields → jsonb columns
rows	`teradata_d_rows`	id PK · linked to teradata_d_tables
schemas	`teradata_d_schemas`	id PK · linked to teradata_d_tables
indexes	`teradata_d_indexes`	id PK · linked to teradata_d_tables

FAQ

How does Datrise handle Teradata's custom fields in PostgreSQL?

Flexible values are stored as jsonb columns, so new fields don't require a migration; strongly-typed fields — dates, numbers, and references — are promoted to native PostgreSQL types.

How does the Teradata to PostgreSQL sync stay up to date?

It runs incrementally — Datrise uses a watermark on each entity's updated-at, applied with INSERT … ON CONFLICT DO UPDATE.
