Yes, an Oracle-compatiblity is important for masks (format pictures)
used in both (Ora and PG). But our PG's implementation has some extensions,
for example 'ID' ISO-day-of-week in 7.2 where Monday = first day of week.
I hope all countries will glad :-)
for 'WW' and 'D' are results same:
Ora:
SVRMGR> select to_char( to_date('2001/03/12', 'YYYY/MM/DD'), 'WW Day D
YYYY/MM/DD') from dual;
TO_CHAR(TO_DATE('2001/03/
-------------------------
11 Monday 2 2001/03/12
1 row selected.
PG:
select to_char( to_date('2001/03/12', 'YYYY/MM/DD'), 'WW Day D YYYY/MM/DD');
to_char
---------------------------
11 Monday 2 2001/03/12
