small bug on 3-digit years in 9.2-dev - Mailing list pgsql-hackers

Hi,

While working on the "What's new in 9.2", I think I found a small bug:

SELECT to_date('519-07-02','YYY-MM-DD'); to_date   
------------0519-07-02
(1 row)

It comes, I think, from the year 519 case not being handled in the following 
code. Patch attached

+    if (year < 70)
+        return year + 2000;
+    /* Force 70-99 into the 1900's */
+    else if (year >= 70 && year < 100)
+        return year + 1900;
+    /* Force 100-519 into the 2000's */
+    else if (year >= 100 && year < 519)
+        return year + 2000;
+    /* Force 520-999 into the 1000's */
+    else if (year >= 520 && year < 1000)
+        return year + 1000;
+    else
+        return year;

Regards
