I can't seem to find any documentation on the --enable-integer- datetimes configure option. Here's a patch that adds a very brief description to section 14.5 Installation Procedure, which lists the other config options.
Here's the description: Use 64-bit integer storage for datetimes and intervals. This guarantees microsecond precision in datetime calculations.
