Обсуждение: hash_destroy on the hash table allocated with TopMemoryContext
Hi,
I was looking for a pattern to destroy a hashtable (dynahash).allocated in TopMemoryContext
I found one pattern : create_seq_hashtable uses TopMemoryContext
I found one pattern : create_seq_hashtable uses TopMemoryContext
memory context to create hash table. It calls hash_destroy in
ResetSequenceCaches. hash_destroy will destroy the memory context(TopMemoryContext). Is it the right way to use hash_destroy ?
I have allocated a hash table in TopMemoryContext context and I want
I have allocated a hash table in TopMemoryContext context and I want
to destroy it. It seems to me that there is no function to destroy hash
table allocated in TopMemoryContext context.

The context used to pass hash_create() is used to create a child memory context. The hash table is allocated in the child memory context and it's that context which is destoryed by hash_destory(). Isn't it?

How did you create hash table in TopMemoryContext?
