“server closed the connection unexpectedly”

The query:

SELECT schemaname, tablename
           FROM pg_tables
           WHERE tableowner IN (E'njvue5kiy1c') OR schemaname='public';

--------
The error:

DBD::Pg::db selectall_arrayref failed: server closed the connection
unexpectedly
    This probably means the server terminated abnormally
    before or while processing the request.

--------

It happens every time. The “njvue5kiy1c” is a random generated name.

Does anyone know what may be causing this?
