Hi, hackers
When I try to insert an Unicode "\u0000", there is an error $subject. postgres=# CREATE TABLE tbl (s varchar(10)); CREATE TABLE postgres=# INSERT INTO tbl VALUES (E'\u0000'); ERROR: invalid Unicode escape value at or near "\u0000" LINE 1: INSERT INTO tbl VALUES (E'\u0000'); ^ "\u0000" is valid unicode [1], why not we cannot insert it?
