Description:        TOKMAXLEN=10 to short for token strings
Details:

Hi!

Structure datetkn in src/include/utils/datetime.h has a character array
token of length 10 (TOKMAXLEN).
In src/backend/utils/adt/datetime.c two arrays of datetkn structures are
filled where some tokens exceed 10 bytes!
On HP-UX using aCC this gives startup errors as:

2008-09-04 07:13:41 GMT   LOG:  ordering error in deltatktbl table: "#mil"
>= "{llennia"
2008-09-04 07:13:41 GMT   LOG:  ordering error in deltatktbl table:
"{millenniu" >= "p{millisec"

To solve this for me i increased TOKMAXLEN to 16.
