hi.
one more patch for regress tests.
ALTER TABLE salespeople MERGE PARTITIONS (salespeople10_20,
salespeople20_30, salespeople30_40) INTO salespeople10_40;
the trigger on the merged partition will be dropped.
For example, here, trigger on salespeople10_20 will be dropped.
I am surprised that partition_merge.sql doesn't have much \d+ command.
so I added two, which is necessary IMHO.
