Destination Improvement: UUID type unsupported in Postgres destination

Planned
Atishi Gupta User

Creating this Feature Request on behalf of the customer.

 

Summary:
Reverse ETL currently does not support writing to columns of type UUID in PostgreSQL destinations. Syncs fail when UUID columns are present, forcing customers to use text-based alternatives.

Impact:

  • Prevents use of native UUID types, constraints, and indexing.

  • Causes schema mismatches and added maintenance overhead.

Customer Ask:
Enable Reverse ETL to write to UUID columns in PostgreSQL, handling automatic casting from text-based UUID values where applicable.

Business Justification:
UUIDs are a common standard for identifiers. Supporting them ensures correctness, referential integrity, and better performance for PostgreSQL users.

Priority:
High — impacts schema design and operational efficiency

    Hi Atishi,

    Thanks for sharing your request. I've created a roadmap item for the feature and will investigate when/how we can implement it. I will be sharing any progress here.

    In the meantime, could you please share which source connector(s) you use to write to Postgres?

    Thanks,
    Val Kulichenko, Fivetran Product Team
