I've created a function for each data type with the idea that an example for handling a specific data type can be more easily reviewed by looking in a single place. I've added examples for REAL, TIMESTAMP WITHOUT TIME ZONE, and BOOLEAN to try to illustrate how testlibpq3.sql and testlibpq3.c will grow if this is a good way to go. Regards, Mark
