While reloading a database cluster to move from 10.5 to 11, I'm getting
out of memory crashes that I did see when doing reloads on pg 10.
The statement flagged in the log is this:
2018-10-23 16:44:34.815 CDT [126839] STATEMENT: ALTER TABLE ONLY public.iplocation
ADD CONSTRAINT overlap EXCLUDE USING spgist (network WITH &&);
iplocation has 4398722 rows.
This is geolite data where the networks are a partial covering of the total
address spaces with no overlaps.
Should I expect to have to make config changes to make this work?
