Uploading a certain raster .tif yields empty tiles and an error:

{ err_id: 2,
 err_msg: 'render vector',
 error: 'pgraster_wkb_reader: grayscale band type 10 unsupported',

This is data from a client, thus it's high priority to support this data type.

[strk]

That error comes from mapnik, filing a ticket there, with a sample of that data, should help

[knutole]

This has nothing to do with lacking support in pgraster.input?

[strk]

It does: PT_32BF grayscale unsupported (hey, that's my TODO!!)

[knutole]

Haha I KNOW! :)

How much work to add support for this?

I don't remeber how much depends on mapnik core and how much
on caller, but I can take a look, just attach a 32BF grayscale
sample on a mapnik ticket, and link from here.
