I agree.
But then, would you agree that it is finally time for us to solve the problem
of having to create multiple versions of a function to handle different data
types.
Why
Karol,
If user code something wrongly or create inifinite loops, wrongly
results he/she will have, no matter how things are defined.
I like your opinion to not limit to only one input parameters. This
limitation seems to not have sense.

Hi,
First – good concept
But, how this will work?
In every WHILE loop, engine will lock loop until next row is „fetched” and
susspend is called?
I do not know if you understand me?
What if function will do not call susspend at all or do not run while loop
properly?
Maybe this can be done

Engine does all the work for groups.

Hi!
I propose creation of user-defined aggregate functions.
Lets initially define the requirements for it:
- It should work with empty data set too, in case of use without GROUP
BY clause: i.e., COUNT results in 0, while most others functions result
in NULL
- It should also produce "running (or
