Hi, I just noticed a difference in output with the to_date() function between 8.3.7 and 8.4.B2.
Running the following query on PG 8.3.7 select to_char(2009,'9999') as year, to_char(3,'09') as month, to_date(to_char(2009,'9999')||to_char(3,'99') ,'YYYYMM') as method1, to_date(to_char(2009,'9999')||'-'||to_char(3,'09') || '-01','YYYY-MM-DD') as method2 results in: year, month, method1, method2 " 2009";" 03";"2009-03-01";"2009-03-01" Running exactly the same query on PG 8.4.B2 gives: year, month, method1, method2 " 2009";" 03";"0200-09-01";"2009-03-01" PG 8.3.7 "method1" = "2009-03-01" PG 8.4.B2 "method1" = "0200-09-01" Both databases were on the same machine - Fedora 10 - 32bit (GCC 4.3.2). Server configured for Australian timezone/usage. I realize I should have slapped a trim() around the to_char(), but thought it worth noting the difference anyway. Cheers, Jeremy.
