Using a test similar to one upthread: select count(*) from (select md5(i::text) as t from generate_series(1,100000) as i) s where t is nfc normalized ; I get (median of three) v4 419ms v5 310ms with binary size v4 HEAD + 33kB v5 HEAD + 57kB -- John Naylor https://www.2ndQuadrant.com/ PostgreSQL Development, 24x7 Support, Remote DBA, Training & Services
