I would like to use copy_to() from dplyr to create a new table. Indexes can be easily specified, but I do not see a syntax for specifying a primary key. Is the recommended approach to simply create the table first and then copy data into it using copy_to() as a second step, or is there a single-step solution way to specify primary key in copy_to()?
How does one specify a primary key when using dplyr copy_to()?

As mentioned by John in the comment, Hadley gave an example of setting index in an old presentation, archived here. His example:
However, indexes are not primary keys. I digged around in the dplyr and dbplyr source code to see if it is possible to specify a primary key. It seems not. I found a half-dplyr solution. Here's a working example.
output:
dplyr doesn't show the indexes or keys, as far as I can tell. So I used DBeaver to confirm:
