Log Message: ----------- Ensure default-only storage parameters for TOAST relations to be initialized with proper values. Affected parameters are fillfactor, analyze_threshold, and analyze_scale_factor. Especially uninitialized fillfactor caused inefficient page usage because we built a StdRdOptions struct in which fillfactor is zero if any reloption is set for the toast table. In addition, we disallow toast.autovacuum_analyze_threshold and toast.autovacuum_analyze_scale_factor because we didn't actually support them; they are always ignored. Report by Rumko on pgsql-bugs on 12 May 2010. Analysis by Tom Lane and Alvaro Herrera. Patch by me. Backpatch to 8.4.
