Description: Misleading info in docs on volatility level of functions
Details:
Hi, all!
The documentation on how to and why declare a function STABLE or IMMUTABLE
is very laconic. It makes clear what promises I make when determining the
volatility of my functions but it fails to point out what exactly I can
expect in turn for my promises.
See also the discussion on bug#2150 on the pgsql-bugs list.
Thanks for bothering.
