Thread: pgsql: Fix MERGE with DO NOTHING actions into a partitioned table.
Fix MERGE with DO NOTHING actions into a partitioned table. ExecInitPartitionInfo() duplicates much of the logic in ExecInitMerge(), except that it failed to handle DO NOTHING actions. This would cause an "unknown action in MERGE WHEN clause" error if a MERGE with any DO NOTHING actions attempted to insert into a partition not already initialised by ExecInitModifyTable().
