MySQL->PostgreSQL

DATE values supported by MySQL range from '1000-01-01' to '9999-12-31'.
DATETIME values supported by MySQL range from '1000-01-01 00:00:00' to '9999-12-31 23:59:59'.

TIMESTAMP values supported by MySQL range from '1970-01-01 00:00:01' UTC to '2038-01-19 03:14:07' UTC.

For details, see official MySQL documentation.

For PostgreSQL, 0000-00-00 is an invalid date and will be converted to 1970-01-01 by DRS. For example, '0000-00-00' of the DATE type in MySQL is converted to '1970-01-01' by DRS, and '1000-00-31 23:59:59' of the DATETIME or TIMESTAMP type in MySQL is converted to '1970-01-01 00:00:00' by DRS.
TIME values supported by MySQL range from '-838:59:59' to '838:59:59'. For details, see the official MySQL documentation. For PostgreSQL, the minimum value of the TIME type is 00:00:00 and the maximum value is 24:00:00. In MySQL, if a value of the TIME type is less than 00:00:00 or greater than 24:00:00, DRS will convert it to 00:00:00.
YEAR value ranges supported by MySQL are 1901 to 2155 and 0000. For details, see official MySQL documentation. PostgreSQL does not have the YEAR type, so DRS will convert the YEAR type of MySQL to the SMALLINT type.
For MySQL databases, '0000' of the DATE type will be converted to 0 by DRS.
If the data type of a column is INT and the column contains the AUTO_INCREMENT attribute, DRS converts the data type of the column to SERIAL during synchronization.
