Welcome to psql 7.3.2, the PostgreSQL interactive terminal.

Type:  \copyright for distribution terms
       \h for help with SQL commands
       \? for help on internal slash commands
       \g or terminate with semicolon to execute query
       \q to quit

urldb=# select replace('whatever%20sitis','si','SI');
    replace    
---------------
 whateverSItis
(1 row)

1. No doc said % should escape by %%, and 
select replace('whatever%20sites','%20','%%20') won't work also.
2. v7.3.2 haven't resolved this problem yet, I am not sure the later version.

I seem to get the expected results on my 7.3.4 system.

In 7.3.3 release notes:

    *  Fix misbehavior of replace() on strings containing '%'
