Now that is weird.
How can the same backend process suddenly be connected to database "citgis" as user "citgis"?
Do you have an explanation?

What is your work_mem setting?
This influences the amount of "private" memory a backend will allocate.

Can you say more that "executes a PL/pgSQL function in a loop" about the workload?
Are there long transactions?

Which version of PostgreSQL is this?
