The 'date' field is a timestamp without timezone. The upper and lower bounds of the BETWEEN are identical just for testing purposes. Any range would do.
I'm having trouble reproducing the problem on a similar data set. I created a new db, same table schema, same row count with randomly generated data for testing but the function works fine. So perhaps my problem is related to the tables rather than the function. If I can successfully reproduce the problem with another data set I'll send example code to share. I'll also look into the links you gave me.
Thanks,

doesn't know that the timestamp range condition is extremely selective.
