This commit adds pg_attribute_encoding entries for root partitions, During create statement, we add attribute encoding entries to catalog If the table has a parent partition, and no options or encodings are specified, we copy the parent partition's encoding entries For partitioned table create statement, we pick the explicitly defined column encoding for the parent over the table-level option defined for the child partition. The storage encoding clause for a column is picked as follows: * 1. An explicit encoding clause in the ColumnDef of self/parent * 2. A column reference storage directive for this column * 3. A default column encoding in the statement * 4. Parent partition's column encoding values * 5. A default for the type. Add attribute encodings to d+ description for root partitions Added tests to check comlumn encoding inheritance priority
