[postgis-users] ESRI Geodatabases, relationship classes and PostGIS

[Lee Hachadoorian]

Yes, ArcCatalog creates a standard Access database table, but enforces
the creation of a unique index called OBJECTID (which is not, however,
actually a primary key).  So what Regina describes should work.

There's an ogr2ogr cheatsheet at BostonGIS
(http://www.bostongis.com/?content_name=ogr_cheatsheet).

I'm not sure about the relationship classes question, although my
suspicion is that the conversion works table-by-table on data (spatial
and non-spatial) only.  Since the relationship classes are not stored
in the feature class or non-spatial table itself (they are stored in a
table called GDB_RelClasses), I suspect that ogr2ogr will not do
anything to convert them.  Can someone confirm?
