Hi, 

I upgraded the version of PostgreSQL from 12.6 to 12.13, 

when I execute the sql below , the to_char function caused the following error.

---------------SQL------------------

select TO_CHAR('1000000');

    Isn't '1000000' already a character string?
    
    How do you convert a character string to a character string?
