Alvaro Herrera 20bef2c311 Fix ALTER/TYPE on columns referenced by FKs in partitioned tables When ALTER TABLE ... SET DATA TYPE affects a column referenced by constraints and indexes, it drop those constraints and indexes and recreates them afterwards, so that the definitions match the new data type. The original code did this by dropping one object at a time (commit `077db40fa1` of May 2004), which worked fine because the dependencies between the objects were pretty straightforward, and ordering the objects in a specific way was enough to make this work. However, when there are foreign key constraints in partitioned tables, the dependencies are no longer so straightforward, and we were getting errors when attempted: ERROR: cache lookup failed for constraint 16398 This can be fixed by doing all the drops in one pass instead, using performMultipleDeletions (introduced by `df18c51f29` of Aug 2006). With this change we can also remove the code to carefully order the list of objects to be deleted.
