I'm having a problem with the transform function in Postgis. If I run
the following query:

select transform(GeometryFromText('MULTIPOLYGON(((112 -45 ,112 -10 ,155
-10 ,155 -45,112 -45)))',4326),54004)

I get:

SRID=54004;MULTIPOLYGON(((12467782.9688466
-5591295.91855339,12467782.9688466 -1111475.10285223,17254521.0729574
-1111475.10285223,17254521.0729574 -5591295.91855339,12467782.9688466
-5591295.91855339)))

But if I do:

select transform(GeometryFromText('MULTIPOLYGON(((-180 -90 ,-180 90 ,180
90 ,180 -90,-180 -90)))',4326),54004)

I get:

Error: transform: couldn't project polygon
Warning: Error occurred while executing PL/pgSQL function transform
Warning: line 2 at return

Any ideas why? I turned the postgresql log level to debug5 to see if I
could get more detailed errors, but it's exactly the same error. I'm
running postgresql 7.3.2, postgis 0.7.5 and proj 4.4.7

Thanks,

Benjamin Wragg
