Agreed, but if that feature(expression) is available in postgresql then users/QA will ask why that is not present in pgAdmin4. If implementation is complex then we could think to include it or not, if we will provide that its upto the user they want to use it or not.
Given that in the expression you used, the variables 'a' and 'b' have undefined values, there's still a chance that we're missing a large chunk of context for successful implementation.
Could you explain what 'a' and 'b' represent?
Where would users find values for 'a' and 'b'? (are they columns?)
a and b are columns.
What is the use case for partitioning by (a+b)/2?
How frequently will people partition this way?
That is just an example of expression, there is no use case for above example.
It's possible to design for the range and list partitions and know we can achieve success because we understand how users would go through this workflow. Not sure about expressions.
