    Stringify a value.

    Stringify a dictionary.

    Convert an iterable to a comma-separated string.

    Sanitize text by removing NUL bytes that are incompatible with PostgreSQL.

    PostgreSQL text fields cannot contain NUL (0x00) bytes, which can cause psycopg.DataError when inserting documents. This function removes or replaces such characters to ensure compatibility.
