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?
