Add a new GUC variable called "IntervalStyle" that decouples interval output
Tom Lane <tgl@sss.pgh.pa.us>
Add a new GUC variable called "IntervalStyle" that decouples interval output from DateStyle, and create a new interval style that produces output matching the SQL standard (at least for interval values that fall within the standard's restrictions). IntervalStyle is also used to resolve the conflict between the standard and traditional Postgres rules for interpreting negative interval input. Ron Mayer
