Hello,
according to the docs
(https://gdal.org/drivers/vector/gpkg.html#relationships) the
geopackage driver is able to read, create, update and delete
"relationships". I tried to convert some tables of a postgis database
to geopackage, but there was no related tables extensions in the
geopackage.
The driver supports the API to read & edit relationships, but ogr2ogr
doesn't have logic to copy relationships from the source dataset to the
target one, nor does the PostGIS implement the relationship API.
The related tables extension is also not listed in the supported
extensions
(https://gdal.org/drivers/vector/gpkg.html#level-of-support-of-geopackage-extensions).
Was missing in that section of the doc. Just added
Is it possible to convert postgis tables to a geopackage with related
tables?
You'll have to use the relationship API to create them manually. Cf
python testing of the GPKG driver:
