FAQs

How do I sync Segment data to PostgreSQL?

Sign up for Weld, connect Segment as a source and PostgreSQL as a destination. Weld handles the extraction, loading, and lets you transform data using SQL or dbt.

What Segment data can I sync to PostgreSQL?

You can sync Contacts, Accounts, Leads, Deals, and Activities. The available objects depend on your Segment account permissions and configuration.

How often does Weld sync data from Segment?

Sync frequency depends on your Weld plan. Schedules range from every 5 minutes to daily intervals. Each sync processes only new and changed data.

Can I transform Segment data before it lands in PostgreSQL?

Yes. Weld supports SQL-based transformations in the platform and integrates with dbt Cloud. You can clean, join, and model your data before analysis.

Is the Segment to PostgreSQL integration secure?

Yes. Weld encrypts all data in transit and at rest, is SOC 2 Type II certified, and supports IP whitelisting. Credentials are stored encrypted and never logged.
