Hello everyone,
we observe a problem when doing some sort of aggregation like

select distinct count(substr(narodene,5,4)) from raw_field;

(raw_field has 1300000 rows)

On executing this query the postmaster grows in memory size until it runs
out of virtual mem and dies.

Any ideas of what is going on and how to avoid this?
