On the contrary, I prefer an obvious indication of "I don't know" to a
value that might appear to be authoritative but is really just a guess.
It could be that one user copied the file verbatim to the branch and a
second user changed the file as part of an unrelated change.

The "default default" value for these commits is "cvs2svn" (in your case
"cvs2git would probably be more appropriate), which I like because it
makes it clearer than "pgsql" that the commit was generated as part of a
conversion.
