I like more specific name like pg_backend_memory_contexts.
But I'd like to hear more opinions about the name from others.

Thanks for updating the patch!
+ <structfield>level</structfield> <type>integer</type>
In catalog.sgml, "int4" and "int8" are used in other catalogs tables.
So "integer" in the above should be "int4"?
+ <structfield>total_bytes</structfield> <type>bigint</type>
"bigint" should be "int8"?
+ Identification information of the memory context. This field is truncated if the identification field is longer
than1024 characters
"characters" should be "bytes"?
It's a bit confusing to have both "This field" and "the identification field"
in one description. What about just "This field is truncated at 1024 bytes"?
+ <para>
+ Total bytes requested from malloc
Isn't it better not to use "malloc" in the description? For example,
what about something like "Total bytes allocated for this memory context"?
+#define PG_STAT_GET_MEMORY_CONTEXT_COLS 9
Isn't it better to rename this to PG_GET_MEMORY_CONTEXTS_COLS
for the consistency with the function name?
+ memset(nulls, 0, sizeof(nulls));
"values[]" also should be initialized with zero?
