I think it is fine actually.  These names appear in structs Query and
PlannedStmt, and every single member of those already uses camelCase
naming.  Changing those to use "query_id" would look out of place.
You did change the one in PgBackendStatus to st_query_id, which also
matches the naming style in that struct, so that looks fine also.

So I'm -1 on Julien's first proposed change, and +1 on his second
proposed change (the name of the first argument of
pgstat_report_query_id should be query_id).
