For test I wrote script in Python, which calls a test function via psycopg2:

#!/usr/bin/env python2

import psycopg2

conn = psycopg2.connect('xxx')

cursor = conn.cursor()

cursor.execute('set application_name to \'TEST\'')

for i in range(1, 1000000):
cursor.execute('select test()')
conn.commit()

I see memory consumption in htop and pg_activity tools.
