The kafka-python instrumentation had to handle it in a bit more complicated way in KafkaInstrumentor.instrumentation_dependencies. Why a similar change is not required here?

@xrmx good catch! This has been updated.

I think would be nice to have this tested at CI, like adding psycopg2-binary package installed in a test-requirements.txt file in the same way was done for kafka-python

Is this what we want tho?

Using pip install opentelemetry-instrumentation-psycopg2[instruments] would install both psycopg2-binary and psycopg2.

We are abusing optional dependencies to do discovery of things, I hope the opentelementry-instrumentation-x[instruments] is not documented anywhere.
