The cause of the memory increase appears to be CacheMemoryContext. When I attached to postgres with gdb and ran "call MemoryContextStats(TopMemoryContext)" several times, the size of CacheMemoryContext kept increasing.
Hmm. I could repeat this, and it seems that the catcache for pg_statistic accumulates negative cache entries. Those slowly take up the memory.
Seems that we should somehow flush those, when the table is dropped. Not sure how, but I'll take a look.
