Comment(by bnordgren):

 Ok, this is what I get for opening my mouth.

 It appears to be more complicated than I thought at first blush (or so
 says the compiler). The bit I need to depend on is the proj4 cache api.
 This part connects to the database to get the proj4 string from the
 spatial_ref_sys table. Whoops. It also depends rather heavily on the
 postgresql memory context. Whoops. Whoops.

 Moving this code to liblwgeom would create a dependency from liblwgeom to
 the core postgresql libraries, and would probably make us compile
 liblwgeom as a postgresql module, if I understand this pgxs thing
 right.... I need to reconfirm with you that this is actually what you want
 to do before I up and do it.
