Just for clarity: In the documentation (http://www.postgresql.org/docs/8.4/static/functions-matching.html#FUNCTIONS-POSIX-REGEXP) is mentioned "Flag g causes the function to find each match in the string, not only the first one, and return a row for each such match. " So in your example it was only matching \r so A\n\tB was returned Cheers, Bastiaan Osvaldo Kussama wrote: > 2010/2/27 <seiliki@xxxxxxxxxxxxx>: > >> Hi! >> >> I am trying to replace characters '\r', '\n', or '\t' with space character ' '.
