- * MemoryContext
- *		A logical context in which memory allocations occur.
- *
- * MemoryContext itself is an abstract type that can have multiple
- * implementations, though for now we have only AllocSetContext.
- * The function pointers in MemoryContextMethods define one specific
- * implementation of MemoryContext --- they are a virtual function table
- * in C++ terms.
- *
- * Node types that are actual implementations of memory contexts must
- * begin with the same fields as MemoryContext.
- *
- * Note: for largely historical reasons, typedef MemoryContext is a pointer
- * to the context struct rather than the struct type itself.
