[raster] Unable to find driver ESRI to unload from GDAL_SKIP environment variable

[strk]

Traces from the first time raster library loads (PostGIS trunk):

2014-06-19 16:40:14.968 CEST psql 8784 strk strk LOG:  statement: select st_asraster(st_point(0,0),1.0,-1.0);

This is with GDAL 2.0.0dev, released 2014/04/16

It sounds like long names are used rather than short names.

[Bborie Park]

We only use short names. The ESRI is really "ESRI Shapefile" which IS the short name for the OGR shapefile driver. Are you specifying "ESRI Shapefile" in postgis.gdal_enabled_drivers GUC? For 2.0, we only look at those drivers with a raster component so no vector drivers are possible.

[strk]

strk=# show postgis.gdal_enabled_drivers;
ERROR:  unrecognized configuration parameter "postgis.gdal_enabled_drivers"

There's no GUC so I think the code that lists all drivers and disables all is being used. In turn, that code is likely getting "ESRI Shapefile" as the name of one driver. How can I check with a commandline ?

[Bborie Park]

A quick way to check is to call raster2pgsql -G on that machine and see if ESRI Shapefile is being emitted. It shouldn't.

[strk]

[strk@cdb:~] raster2pgsql -G | grep ESRI
  ESRI .hdr Labelled
  ESRI Shapefile
  ESRI Personal GeoDatabase
  ESRI FileGDB

Interesting. I'll try to reproduce once I update my GDAL.

[rouault]

With 2.0, as GDAL_SKIP can now handle vector driver names as well, and that a few vector driver names include space, the separator for driver names should be comma (but still space in GDAL 1.X).

But as underlined by dustymugs, if you only iterate on drivers with a raster capability, those vector drivers shouldn't be listed at all

[Bborie Park]

Closing as I can't reproduce this on GDAL 2.0 with r13487.
