There's a comment in dumpExtension() that explains it.
/*
* In a regular dump, we use IF NOT EXISTS so that there isn't a
* problem if the extension already exists in the target database;
* this is essential for installed-by-default extensions such as
* plpgsql.
*
* In binary-upgrade mode, that doesn't work well, so instead we skip
* built-in extensions based on their OIDs; see
* selectDumpableExtension.
