I suppose one place that could be affected visibly is JSON object construction (json.c, jsonfuncs.c) that could potentially deal with millions of stringinfo manipulations, but most of those calls don't actually use appendStringInfoString with constant values, so it's probably not worth bothering with. -- Álvaro Herrera https://www.2ndQuadrant.com/ PostgreSQL Development, 24x7 Support, Remote DBA, Training & Services
