What eats up your memory is "psql", which indeed allocates a whopping
19G physical memory, not the server process.
- Are you sure that is _your_ "psql" selecting "* from customers" and
not somebody else's, doing a cross-join?
- Is there potentially anything that gets TOASTed in your "customer"
table? I'm not sure if that would show up in pg_relation_size and
friends, but it would get sent to psql of course.
