An answer may be to build my own replace function, that doesn't use constant evaluation inside. For instance: CREATE OR REPLACE FUNCTION myreplace(sText varchar, sSrc varchar, sDst varchar) RETURNS varchar AS $BODY$ BEGINRETURN replace( sText, sSrc, sDst ); END; $BODY$ LANGUAGE 'plpgsql' VOLATILE; Using this function will give the expected result, when standard_conforming_strings = 'on', so SELECT myreplace( 'a\b', '\', '\\' ); will give the result 'a\\b' as expected. In fact this is an workaround :((. It would be nice to make the language to works like that :). Regards, Sabin
