Re: Server goes to Recovery Mode when run a SQL

*Well, now we have two queries which stops completelly our postgres server.
That problem occurs on 10.6 and 11.1 versions.
On both server the problem is the same.
Linux logs of old crash are:*

*And this new query which stops the server too but differently because the
old one stops immediatelly instead of this, as you can see images.*
*This query runs for aproximately 5 minutes. See link above with images and
logs and you´ll see how memory will grow. Memory use starts with 8gb e grows
until use them all. When all memory is in use then it starts to swap. When
all swap is allocated then it gets the "out of memory" and stops
completelly. You'll see that this query has generate_series, with, recursive
and lateral statements. It was bad written because that generate_series
generates a enormous quantity of records, probably millions of them. But a
wrong query couldn´t stop the entire server, could ?*
