The following bug has been logged on the website:
Bug reference: 11883
Logged by: Bruce Hunsaker
Email address: hunsakerbn(at)familysearch(dot)org
PostgreSQL version: 9.3.5
Operating system: Linux
Description:
Entering historical dates we found we could not enter a date of '1500-02-29'
Even though 1500 is documented to be a leap year. Tested with date and
timestamp column types.
To reproduce:
psql> create table date_test (mydate date);
CREATE TABLE
psql> insert into date_test values ('1500-02-29');
ERROR: date/time field value out of range: "1500-02-29"
LINE 1: insert into date_test values ('1500-02-29');
psql> insert into date_test values ('1500-02-28');
INSERT 0 1;
So, Feb 29, is not allowed but Feb 28 is.
