Peter Eisentraut 208d3a7555 Correct/improve the datetime_precision field in the information schema.
In particular, always show 0 for the date type instead of null, and show
6 (the default) for time, timestamp, and interval without a declared
precision.  This is now in fuller conformance with the SQL standard.

Also clarify the documentation about this.
