I am running postgres with docker-compose, but when I execute EXPLAIN(ANALYZE, VERBOSE, BUFFERS) with the following SQL statement, I get the following error.
At the same time, I looked at the CPU and memory status, but there didn’t seem to be any problems.
I use pgroonga for image, which is a postgres image with postgres extensions for fast full-text search.

server closed the connection unexpectedly
This probably means the server terminated abnormally
