Álvaro, you hit the nail on the head!

I have seen that in stdio.h BUFSIZ is defined like 1024 in freeBSD 9.0,
probably for this reason I can't test this query (1657 characters), but
I'm able to test shorter queries.

Finally I have done a plsql procedure to call the query from pgbench.
Meanwhile I will try to figure out if I can increase this variable
without affect the system.

Thanks to all
