Hey,
In patch v5 (attached), I changed the approach to class caching.
Now, for small texts (less than 512 characters), we don't allocate
memory from the heap; we use the stack.
And according to pgbench tests, we have a 2x speedup.
According to Jeff's tests, we have a 10x speedup.
According to tests from the thread
https://www.postgresql.org/message-id/CAFBsxsHUuMFCt6-pU+oG-F1==CmEp8wR+O+bRouXWu6i8kXuqA@mail.gmail.com,
we also have a 2x speedup.
