error '??HELP??' binding timestamp as a parameter

[watercraft]

I got the following error trying to pass a timestamp as an argument using a structure with sqlx:
Error: [22007] Invalid input syntax for timestamp: "??HELP??"
Here is an example patch that seems to address the issue.
Note, I'm not using RFC3339Nano here because Vertica doesn't like timestamps we precision beyond what it supports.
