-lco GEOMETRY_NAME ignored when importing FileGDB (with not null constraint on geometry column) to PostGIS

[saultdon]

I rebuilt GDAL this morning from ​https://svn.osgeo.org/gdal/branches/2.0/gdal and I tried to update or replace existing table in a PostGIS database. I tried DROP CASCADE original table and copy a new table when -update didn't work but it ignores the -lco GEOMETRY_NAME=geom flag.

The datasource I have is a FileGDB and trying to insert a table into a PostgreSQL 9.5/PostGIS 2.2.1.

The command I'm using is:

ogr2ogr -gt 65536 -f PostgreSQL pg:"host=${host} dbname=${db} port=${port}" dgtl_road_atlas.gdb DGTL_ROAD_ATLAS_MPAR_SP -nln ${schema}.dra_mpar_sp -nlt PROMOTE_TO_MULTI -progress -lco GEOMETRY_NAME=geom -a_srs "EPSG:3005" -unsetFid

But the resultant GEOMETRY columns name is "geometry" - which is the name of the GEOMETRY column inside the source FileGDB.

ogrinfo -ro -so pg:"host=${host} dbname=${db} port=${port}" bcgov.dra_mpar_sp                         :(  =98%
INFO: Open of `pg:host=${host} dbname=${db} port=${port}'
      using driver `PostgreSQL' successful.

FID Column = ogc_fid
Geometry Column NOT NULL = geometry
...

So it looks like it could be using the geometry column name from the input data source because it's not falling back to the wkb_geometry default.

My data source is a 261 MB FileGDB from ​ftp://ftp.geobc.gov.bc.ca/sections/outgoing/bmgs/DRA_Public/dgtl_road_atlas.gdb.zip

It looks like this specific FileGDB is causing problems.

The geometry column is being created in PostGIS as:

geometry geometry(MultiLineString,3005) NOT NULL

Whereas other FileGDBs that I've tested are working as expected and being created as:

geom geometry(MultiLineString,3005)

There is something different about the source datasets geometry column.

In the dgtl_road_atlas dataset (the one giving troubles) ogrinfo reports it as:

Geometry Column NOT NULL = geometry

And one of the working FileGDB reports the goemetry column as:

Geometry Column = SHAPE

This is a 2.0 regression. Can be workarounded by specifying -forceNullable on the ogr2ogr command line
