Craig,

I have confirmed and fixed this memory leak in CVS.  It turns out the
FetchSRS() method was not incrementing nKnownSRID so the destructor
was never trying to release the spatial reference.

I also found that the CVS code in OGRPGTableLayer::GetSpatialRef() was
not querying against the proper schema field and so in fact spatial
references were never successfully fetched in the CVS OGR version.
I'm not sure if this is a recent problem or not ... I think the schema
support is pretty recent.

This is also now fixed.

Best regards,
