What I want to do is basically print "xxxx" for "asda" or "xxxxxx" for "forget". The number of characters should be same.
what I have tried in sql
Suppose I run
select length("adsa")
I get 4
and when I run this :
select repeat('x', 4);
I get xxxx
Now when I try doing this :
select repeat('x', select length("adsa"));
It throws error. Where am I going wrong ?

You don't need the select
at all in the second argument:
select repeat('x', length('adsa'));
I would also recommend using single quotes for all string constants.

This works for me:
select repeat('x', (select length("adsa")));
just wrap your last select in brackets.
If you are working against a table you can leave out the extra brackets:
select repeat('x', length(my_col))
from my_table
