Yes, I saw it, but that statement is flat out wrong.  SPF records _can_ be 
stored as TXT records, but there is also a dedicated SPF RR type (with 
code 99), which is actually _preferred_ over TXT.  See RFC 4408, section 
3.1.1[1] and section 4.5[2].

And when Bert wrote that he implemented "SPF records support" a few months 
back, I'm pretty sure he didn't mean to say he implemented TXT records in 
PDNS.
