Hello everyone again!
This is the continuation of my previous patch on the same topic; here
there are changes made thanks to Tom Lane comments (see thread here
[1]). To not send big patch I have split it (that's why version starts
with the first again) and here I send infrastructure patch which
includes:
- creation of CachedExpr node
- usual node functions for it
- mutator to replace nonovolatile functions' and operators' expressions
by appropriate cached expressions.
Any suggestions are welcome!
