PostgreSQL

tap-postgres (airbyte variant)🥈

PostgreSQL database extractor

The tap-postgres extractor pulls data from PostgreSQL that can then be sent to a destination using a loader.

Airbyte Usage Notice

This connector uses tap-airbyte-wrapper to call the underlying Airbyte source Docker container. This means you must have Docker installed and running prior to usage. We also recommend using Meltano version 2.13.0 or later.

Container-based connectors can introduce deployment challenges including the potential need to run Docker-in-Docker (not currently supported by services like AWS ECS, Meltano Cloud, etc. see FAQ and Airbyte's ECS deployment docs for more details). Before using this variant we recommend considering if/how you will be able to deploy container-based connectors to production.

For more context on how this Airbyte integration works please checkout out the FAQ in the Meltano Docs.

Capabilities

The current capabilities for tap-postgres may have been automatically set when originally added to the Hub. Please review the capabilities when using this extractor. If you find they are out of date, please consider updating them by making a pull request to the YAML file that defines the capabilities for this extractor.

This plugin has the following capabilities:

  • about
  • catalog
  • discover
  • schema-flattening
  • state
  • stream-maps

You can override these capabilities or specify additional ones in your meltano.yml by adding the capabilities key.

Settings

The tap-postgres settings that are known to Meltano are documented below. To quickly find the setting you're looking for, click on any setting name from the list:

You can also list these settings using 

meltano config
with the list subcommand: 

meltano config tap-postgres list

You can override these settings or specify additional ones in your meltano.yml by adding the settings key.

Please consider adding any settings you have defined locally to this definition on MeltanoHub by making a pull request to the YAML file that defines the settings for this plugin.
