[GENERAL] is it a bug?

[He weiping]

I'm using cvs-current, and testing those build-in function according to the docs. but it seems the "lpad", "rpad" don't work, when I type: select lpad('laser', 4, 'a'); in psql, the result is still 'laser', the same with 'rpad', Is it a bug or I'm mis-understaning the lpad and/or rpad functions?   Regards   Laser
