well, but then again, I want the default value of that field to be 1
greater than the max value, not the next value in a sequence.
The client application has the ability to change the value of that
field, but new records need to be max+1.
So I guess to make pg_dump happy, and to solve potential concurrency
issues, I need a trigger for that field? Or will I have the same
circular reference problem with a trigger?
