autovacuum: handle analyze for partitioned tables Previously, autovacuum would completely ignore partitioned tables, which is not good regarding analyze -- failing to analyze those tables means poor plans may be chosen. Make autovacuum aware of those tables by propagating "changes since analyze" counts from the leaf partitions up the partitioning hierarchy.
This also introduces necessary reloptions support for partitioned tables (autovacuum_enabled, autovacuum_analyze_scale_factor, autovacuum_analyze_threshold). It's unclear how best to document this aspect.
