Hey, I saw that some comments in the recent commit have inconsistent styles??maybe we can tweak them to make them uniform!
```c
// pg_dependencies - output routine for type pg_dependencies.
pg_dependencies_out - output routine for type pg_dependencies.
// pg_ndistinct
// output routine for type pg_ndistinct
pg_ndistinct_out
output routine for type pg_ndistinct
```
