The suggested temporary workaround was to switch affected streams to Full Refresh sync mode until the issue is resolved. General CDC Requirements to Keep in Mind
Regardless of Postgres version, the documentation notes several CDC requirements that apply: [CDC requirements]
⢠CDC requires Postgres v10 or above
⢠Incremental CDC sync is only supported for tables with primary keys
⢠Data must be in tables, not views
⢠Schema changes are not automatically supported in CDC mode Beyond the CDC issue above, the knowledge sources do not contain additional information specifically about known incompatibilities or bugs unique to PostgreSQL 17 as a source. If you are experiencing issues, it may be worth checking the latest connector version and the Airbyte GitHub issues tracker for the most up-to-date information. š 0 button š 0 button ā¹ļø Tip: Mention @kapa.ai in the thread for follow-ups or DM the app for 1-to-1 help.kapa.ai

This caused incremental CDC syncs to show 0 records loaded after the initial sync, while full refresh syncs worked correctly. The issue was escalated to Airbyte's engineering team. [CDC Sync Fails Issue]
3. PgJDBC Compatibility Issue (CDC): There is also a known issue with source-postgres versions 3.6.19 and later where the PgJDBC driver version (42.7.4) causes problems with Debezium CDC, leading to repeated pipeline failures or full re-syncs. The proposed workaround is to downgrade to source-postgres 3.6.18 or downgrade the PgJDBC version to below 42.7.0. This issue is not specific to PostgreSQL 17 but would affect it as well. [CDC Not Working 3.6.22]
In summary, while PostgreSQL 17 is technically within the supported version range, there are active known issues with CDC syncs that may affect it. If you're experiencing problems, switching to Full Refresh mode is a suggested temporary workaround, or downgrading the source-postgres connector to v3.6.18. š 0 button š 0 button ā¹ļø Tip: Mention @kapa.ai in the thread for follow-ups or DM the app for 1-to-1 help.Matt Bayley
