If by destruction you mean something different than pfree, then maybe hash_remove in a loop is the best solution, the other idea being passing a function pointer to hash_destroy_deep to call on each element, which is probably too messy an API.
Yes, callback function is needed, either in HASHCTL or as argument to deep_free().
In any case it's not likely that there are going to be thousands of prepared statements, so is this really an issue?
I think the issue is here that its very common thing to do, so open-coding it everywhere is waste, there should be some utility function for that. void hash_foreach(HTAB, void (*cb_func)(void *)); -- marko ---------------------------(end of broadcast)--------------------------- TIP 9: In versions below 8.0, the planner will ignore your desire to choose an index scan if your joining column's datatypes do not match
