How to 'print a table' in the middle of a plpgsql function

I am deep into debugging some pretty extensive plpgsql and it would be nice sometimes if I could somehow output the
contentof a table to the psql console at a particular point in a function. 

For example, I am executing a select that is not returning the expected row.  So I am wondering, what exactly was in
thetable at the time the query was performed. 

Of course, I could just write a loop prior to my query with a bunch of raise notice statements, but I'll get a stack
tracefor each one.  So that won't be pretty. 

Suggestions?  Thx.
