- pgaql long value corrupted using htons

Hi,

1. I am having trouble writing long values via c interface .testlibqp-dt.c  is attached.
. 2 is being inserted as 8589934592.

qsf=> select * from t1;
   curdate   |  strf  |        intf        |         tm_new         | txnid 
------------+--------+--------------------+------------------------+-------
1999-01-10 | hello2 |8589934592 | 1999-01-08 04:05:06-05 |     3

I tried htobe64 but that didn't help either.
Any advise would be appreciated.

2. I have switched to using string for data and timestamp and it seems to work.

I found functions like TimestampTzGetDatum,time_t_to_timestamptz in the code 
But it seems they are not exposed to interface.
I have the date time in unix format (via time and gettimeofday). I would prefer to pass those values
in binary, rather than string format. Is there any option to do this ? Or is it easily addable?

thanks
Neeraj
