Right. So it appears the right function to use here is pq_sendcountedtext(). However, this sends the strings without null termination, so we'd have to do extra processing on the receiving end. Or we could add an option to pq_sendcountedtext() to make it do what we want. I'd rather stick to standard pqformat.c functions for handling the protocol. -- Peter Eisentraut http://www.2ndQuadrant.com/ PostgreSQL Development, 24x7 Support, Remote DBA, Training & Services -- Sent via pgsql-hackers mailing list (firstname.lastname@example.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
