Getting statement handle attributes from dbdimp.c

-----BEGIN PGP SIGNED MESSAGE-----
Hash: RIPEMD160


DBD::Pg gathers up information for foreign_key_info 
and then uses DBD::Sponge to turn it into a statement 
handle which is passed back to the caller. The problem 
is that the imp_dbh has a user-settable flag (pg_expand_array) 
which should always be off inside of dbd_st_fetch. What 
I need is some way to detect, inside of dbdimp.c, that the 
statement handle (imp_sth at this level) came from DBD::Sponge. 
Either inside of fetcth itself, or perhaps better, at an earlier 
stage so that I can set one of the internal imp_sth fields 
(imp_sth is a struct that is initialized in perpare). Any ideas 
on how to do this? In Perl, it's as easy as:

if ('sponge' eq $sth->{Database}{Driver}{Name})

but getting that information inside of dbdimp.c is the bit 
I cannot figure out.
