Yes, palloc allocates memory in contexts, and the memory allocated in these contexts by palloc are freed at the
deletionof the context.

And that as well directly in the docs:
http://www.postgresql.org/docs/devel/static/xfunc-c.html#AEN53984
"The memory allocated by palloc will be freed automatically at the end
of each transaction, preventing memory leaks."
