Hi Nick,

I ran into your email while tracking this down myself, and I can't
find that it ever got answered.  So hopefully better late than never.

This difference is just a cosmetic difference and is harmless.  It was
introduced by a change made in PostgreSQL in the point releases of
2012-08-17 (9.1.5, 9.0.9, etc.).  It was commit
aa7cd144062bef3baf8fd4548c0f54bb108c3270, if you wish to see the
details.

Postgis immunized against this change in commit r10234, which is in
the development branch of Postgis and not yet released.  The comments
for that commit say it is for a PostgreSQL change in 9.2rc1, but that
same change actually showed up in all of the PostgreSQL back branches
as well.

Cheers,

Jeff
