Hi,
I have a question about a correct way of preserving state/some
information across pg functions call
Let's imagine following example:

External C functions:

FUNCTION_INIT_SOMETHING     - allocates a memory, returns some kind of
handle
FUNCTION_DO_SOMETHING      - use allocated memory
FUNCTION_FREE_SOMETHING  - deallocate using handle

and of cause general idea automatic deallocation at the and of session
scope
Thank you.
