I’m having trouble finding any real source code. Obviously I’m looking at the wrong paths, but I was curious if somebody could please give me the classpath to some postgres connector code? I’m interested in how auth is handled as well various other items. Thanks so much!

Currently, we're using Singer taps and targets behind the scenes for most of the connector code. We'll probably depend on it less over time for our core connectors, but we'll probably have some sort of compatibility long-term.

https://github.com/airbytehq/airbyte/blob/master/airbyte-workers/src/main/java/io/airbyte/workers/protocols/singer/SingerCheckConnectionWorker.java is the entrypoint for calling the discovery process on an integration and interpreting the result as a successful or failed connectioon.

https://github.com/airbytehq/airbyte/tree/master/airbyte-integrations/singer/postgres/source and https://github.com/airbytehq/airbyte/tree/master/airbyte-integrations/singer/postgres/destination are where the actual Postgres Singer tap and target are wrapped as Docker images.

For the source we're using

singer-io/tap-postgres

which uses

psycopg2

for the connection https://github.com/singer-io/tap-postgres/blob/master/tap_postgres/db.py#L47

For the destination we're using

datamill-co/target-postgres

which uses

psycopg2

as well under the hood: https://github.com/datamill-co/target-postgres/blob/master/target_postgres/__init__.py#L13

Is that what you were looking for?
