Yes, I'm okay with these changes. Thanks for the review!

I didn't know about the rule regarding local-use enums without typedef,
as there are examples like pgssVersion and pgssStoreKind in pg_stat_statements.c.
However, I guess that keeping typedefs.list small is better.
So, I'm fine with removing the typedef from that enum definition
and updating typedefs.list accordingly.

You're right. I made the change for readability, as similar
functions in pg_stat_statements are implemented that way.
However, it's not essential. I'm okay with reverting it.
