Not an example, but have a look at the COPY command:

http://www.postgresql.org/docs/8.3/interactive/sql-copy.html

COPY FROM stdin lets you insert data in bulk, without having to issue a 
new INSERT for every row.  There are some handy libpq functions for 
feeding data into this mechanism:

The "binary" part of what you're asking for is also possible, but 
probably doesn't buy you all that much.  Chances are you'd need to do 
some conversions anyway, and it introduces all sorts of maintenance risk 
for an optimization that's not likely to matter as much as disk flushes, 
network transfers etc.
