PostgreSQL version: 11.7
Operating system: RHEL 7.7
Description:
PostgreSQL crashes if you do the following:
$psql postgres -c 'create extension lo'
CREATE EXTENSION
$psql postgres -c 'select lo_manage()' server closed the connection
unexpectedly
This probably means the server terminated abnormally
before or while processing the request.
connection to server was lost

I do know that lo_manage requires an argument, but it should not create a
segmentation fault even though the argument is not provided.
