Maybe all the stuff ala fprint perform better in C rather than building up a string concatenating and escaping in php. Still I wouldn't consider it a first source of slowdown. For making a difference in plan management you've to use another family of functions pg_prepare/pg_execute. I'm not an expert but not every time caching plans is what you'd like to do. -- Ivan Sergio Borgonovo http://www.webthatworks.it
