CustomType currently only works for bytes.
This is a good idea that has been discussed in these issues.
#28
#36
I would really love to have this done for all scenarios, since I believe customtype is very useful for more than just bytes.
Maybe you would like to join a discussion so that we first design a good solution for this problem.

PS
Please do not import other projects, even in tests.
I am trying to keep the dependencies to a minimum.

I think my main problem was something with NewPopulated.
I think I can probably just let go and do something more practical.

Oops, removed the usage of the cockroach/util package. That was just some copy&paste of existing code.

I'll add a comment to #36 which is the exact issue this PR is addressing.

Cool :)

I hope the proposed casttype will fix this issue for you?
#36

Please open again if you think this is still relevant.
You might be able to reuse some of this work if you would like to implement casttype.
