simple example of copying data from a c/c++ array into postgres

2008-12-03         2.6585

2008-12-04         2.5513

2008-12-05         2.7037

2008-12-08         2.7378

my script does something like this:

insert into kls_clnt.obs (id, asofdate, datavalue) values (100, 2008-12-03, 2.6585);

for every row of the data.

Since, I already have this data in a C array, it must be faster to iterate through the rows of the array and persist the data directly from C to the database.   Can someone direct me to a simple example of doing this?

Thanks,

Whit
