If you're only using Transaction Mode on Connection Pooler port 6543 or already using Session Mode on port 5432 then no action is required.
On February 28, 2025, Supavisor (Supabase's Connection Pooler) is deprecating Session Mode on port 6543. After this date, port 6543 will only support Transaction Mode while port 5432 continues to support Session Mode.
We’re making this change because Session Mode is already available on port 5432 and this streamlines our connection pooler’s ports and their respective modes.
Required steps:
- Update your application/database clients to use port 5432 for Session Mode.
- In your project’s Database Settings (”Connection pooling configuration”), set “Pool Mode” to “Transaction” and click “Save” (please keep in mind that this will restart all your connections connected to the Pooler).
Please reach out to our support if you have any questions or concerns regarding this change.
