Base table FILLFACTOR is not 100

Query goal: Find all base tables where FILLFACTOR is not 100, i.e., the default value.
Notes about the query: The query assumes that if the FILLFACTOR has been changed to other value than 100 and then back to 100, then the corresponding reloption is still registered. There are more than one possible reloptions. Thus, instead of using the condition reloptions IS NOT NULL, the query filters out reloptions that specify a new FILLFACTOR value.
