Ok, I'll consult the ALTER DATABASE SET codes.

Storing in arrays might make it difficult to retrieve relations that match
conditions specified by clients. However, I think such queirs are not used
so many times. And if necessary, we can provide a helper function to extract
a value from an array, like "valueof(reloptions, 'fillfactor') > 90"
