invalid frontend message type 112

Hi

I have forked postgres-async-driver with the goal to contribute some changes to the DataConverter class, but I am unable to get the current master to run.

Here's the exception I get when trying to query my local postgres instance or run the postgres-async-driver test suite:

Everything is working just fine when I use the current version from Maven Central (0.6).

My setup:

• Mac OSX 10.10.5
• postgres 9.4
• java 1.8.0_60-b27

Any idea how to I can fix this?

Hi, thanks for the bug report. :)

You are probably using trust authentication and that should now be fixed.

Note that AuthenticationTest will still fail for you from the test suite as it currently requires md5 auth in pg_hba.conf.

Thanks for fixing this one so fast. You're awesome :+1:

Adding md5 auth to my pg_hba.conf also fixed the tests for me. Thanks for the hint!
