[pgpointcloud] PDAL error

[Paul Ramsey]

No, what’s happening is that PDAL is generating a Schema object based on the LAS files, and then serializing that object to XML to hand to pointcloud. Pointcloud is getting that document and going “huh?” and not successfully parsing it. Something is changed with the Schema object -> XML document step in PDAL, which is consistent with your having changed the version of PDAL you’re using.

I believe it is a PDAL issue as it worked before with the same XML and las/laz files before the new version was installed. Could it be a compiler issue?

Looks like libxml is failing to parse the XML document PDAL is generating, which is odd, because the failure is at the basic XML parse level, not at any further level. So this is a particular problem w/ the XML generated (or not) by PDAL, possibly because the API contract there changed? So more of a PDAL problem, perhaps, than a pointcloud one.

So we compiled the latest version of PDAL and installed, but now I can't get pipeline to work right. The reason we updated was to take advantage of the multi-filter and scaling features (which seem to work great). When I try to pipeline las/laz files into PostGIS I get this:  

$ pdal pipeline laz2pg.xml
