When running the below statement that takes more than 30 minutes (31 minutes) using psycopg2 the execution ends in the PostgreSQL server but the python routine not ends:

do $$
declare
  v_minutes int := 31;
begin

  perform pg_sleep(60 * v_minutes);

end $$;

print("start of execution")
try:
    cur  = conn.cursor()
    cur.execute(statement)
finally:
    if cur:
        cur.close()
print("end of execution")

In the PostgreSQL logs I got at 30 minutes of execution: "could not receive data from client: connection reset by peer"

If I run the statement with 29 minutes for example... it works ok.
