This page guides you through the process of setting up the Postgres destination connector.


To use the Postgres destination, you'll need:

  • A Postgres server version 9.5 or above

Airbyte Cloud only supports connecting to your Postgres instances with SSL or TLS encryption. TLS is used by default. Other than that, you can proceed with the open-source instructions below.

You'll need the following information to configure the Postgres destination:

  • Host - The host name of the server.
  • Port - The port number the server is listening on. Defaults to the PostgreSQL™ standard port number (5432).
  • Username
  • Password
  • Default Schema Name - Specify the schema (or several schemas separated by commas) to be set in the search-path. These schemas will be used to resolve unqualified object names used in statements executed over this connection.
  • Database - The database name. The default is to connect to a database with the same name as the user name.
  • JDBC URL Params (optional)

Refer to this guide for more details

Configure Network Access

Make sure your Postgres database can be accessed by Airbyte. If your database is within a VPC, you may need to allow access from the IP you're using to expose Airbyte.

Step 1: Set up Postgres


You need a Postgres user with the following permissions:

  • can create tables and write rows.
  • can create schemas e.g:

You can create such a user by running:

CREATE USER airbyte_user PASSWORD <password>;

You can also use a pre-existing user but we highly recommend creating a dedicated user for Airbyte.

Step 2: Set up the Postgres connector in Airbyte

Target Database

You will need to choose an existing database or create a new database that will be used to store synced data from Airbyte.

Naming Conventions

From Postgres SQL Identifiers syntax:

  • SQL identifiers and key words must begin with a letter (a-z, but also letters with diacritical marks and non-Latin letters) or an underscore (_).

  • Subsequent characters in an identifier or key word can be letters, underscores, digits (0-9), or dollar signs ($).

    Note that dollar signs are not allowed in identifiers according to the SQL standard, so their use might render applications less portable. The SQL standard will not define a key word that contains digits or starts or ends with an underscore, so identifiers of this form are safe against possible conflict with future extensions of the standard.

  • The system uses no more than NAMEDATALEN-1 bytes of an identifier; longer names can be written in commands, but they will be truncated. By default, NAMEDATALEN is 64 so the maximum identifier length is 63 bytes

  • Quoted identifiers can contain any character, except the character with code zero. (To include a double quote, write two double quotes.) This allows constructing table or column names that would otherwise not be possible, such as ones containing spaces or ampersands. The length limitation still applies.

  • Quoting an identifier also makes it case-sensitive, whereas unquoted names are always folded to lower case.

  • In order to make your applications portable and less error-prone, use consistent quoting with each name (either always quote it or never quote it).

Note, that Airbyte Postgres destination will create tables and schemas using the Unquoted identifiers when possible or fallback to Quoted Identifiers if the names are containing special characters.

For Airbyte Cloud:

  1. Log into your Airbyte Cloud account.
  2. In the left navigation bar, click Destinations. In the top-right corner, click new destination.
  3. On the Set up the destination page, enter the name for the Postgres connector and select Postgres from the Destination type dropdown.
  4. Follow the Setup the Postgres Destination in Airbyte

Supported sync modes

The Postgres destination connector supports the following sync modes:

Full Refresh SyncYes
Incremental - Append SyncYes
Incremental - Deduped HistoryYes

Schema map

Output Schema

Each stream will be mapped to a separate table in Postgres. Each table will contain 3 columns:

  • _airbyte_ab_id: a uuid assigned by Airbyte to each event that is processed. The column type in Postgres is VARCHAR.
  • _airbyte_emitted_at: a timestamp representing when the event was pulled from the data source. The column type in Postgres is TIMESTAMP WITH TIME ZONE.
  • _airbyte_data: a json blob representing with the event data. The column type in Postgres is JSONB.
