Bulk data insertion

Hello,

I have a PL/PgSQL function that I need to call with some ARRAY
parameters.  These array values are very large -- typically thousands of
elements.  Each element is a 4-element array.  This function is called
to do some sanity checking on the array data and use the individual
elements to do inserts where appropriate.

The problem is that I don't want to spend a lot of time and memory
building such a query (in C).  I would like to know if there is a way to
take this huge chunk of data and get it into the database in a less
memory-intensive way.  I suppose I could use COPY to put the data into a
table with triggers that would do the checks on the data, but it seems
inelegant and I'd like to know if there's a better way.

Thoughts?  Thanks for your time.
