+ * All in this version is implemented as keywords ( => not used
+ * suffixes), because a format picture is for *one* item (number)

+ * has suffix.
+ *
+ * NOTE for DateTime version:
+ * In this modul is *not* used POSIX 'struct tm' type, but
+ * PgSQL type, which has tm_mon based on one (*non* zero) and
+ * year *not* based on 1900, but is used full year number.
+ * Modul support AC / BC years.
+ *
+ * Supported types for to_char():
+ *
+ * DateTime, Numeric, int4, int8, float4, float8
+ *
+ * Supported types for reverse conversion:
+ *
+ * Datetime - to_datetime()
+ * Date - to_date()
+ * Numeric - to_number()
