> CREATE OR REPLACE FUNCTION myreplace(sText varchar, sSrc varchar, sDst ... Unfortunatelly this is not very productive when sSrc or sDst has to be constants inside the function. There is another workaround for that, to specify '\' as chr(92). For instance: CREATE OR REPLACE FUNCTION myformat(sText varchar) RETURNS varchar AS $BODY$ BEGIN RETURN replace( sText, chr(92), '\\' ); END; $BODY$ LANGUAGE 'plpgsql' VOLATILE; Consequently, the statement SELECT myformat('a\b' ) will get the desired result a\\b Sabin ---------------------------(end of broadcast)--------------------------- TIP 5: don't forget to increase your free space map settings
