Hi

  It is why I am asking - the patch does not have a detail
description in text, it is not clear what and why is changed.

  What do you mean, when speak about function cache?
What object or function allocate it? I wrote
in my previous email, that function does not have any
cache, it deallocates after the execution everything allocated
and does not have cache. Cached plans are not function cache,
it is the cache of plans for future use by any other functions
or simple query with the same generic or custom plan. They all
are deallocated at least when user decides to close the connection.

Could you clarify, what function cache do you mean?
