<p>Hi,</p>
<p>as as follow-up, the mentioned below capacity is now in GDAL
master per <a href="https://github.com/OSGeo/gdal/pull/3638" target="_blank">https://github.com/OSGeo/gdal/pull/3638</a><br>
</p>
<p>This is implemented curretly for FileGeodatabase (reading-only,
could be extended on the write side in the FileGDB) and GeoPackage
(read/write).</p>
<p>I guess this could be extended to PostgreSQL too by storing the
enums in an auxiliary table linked through a foreign key.</p>

<div dir="ltr">Hi,
<div>I'm trying to dump a large PostGIS database into a
GeoPackage. In the original database some columns</div>
<div>are strings, but could be more efficiently represented as
enums, as they have a small set of values.</div>
<div><br>
</div>
<div>GeoPackage has a native notion of enums, check the spec and
search for "table 27" for an example:</div>
<div><a href="http://www.geopackage.org/spec/" target="_blank">http://www.geopackage.org/spec/</a><br>
</div>
<div><br>
</div>
<div>However I cannot find mention of them in the GPKG driver
documentation:</div>
<div><a href="https://gdal.org/drivers/vector/gpkg.html" target="_blank">https://gdal.org/drivers/vector/gpkg.html</a><br>
</div>
<div>I quickly grepped into the geopackage sources for "enum",
could not find it in the geopackage sources.</div>
<div><br>
</div>
<div>Also looked at the "mapFieldType" ogr2ogr parameter and at
OGR SQL, did not find anything there either.</div>
<div><br>
</div>
<div>So I'm wondering, is there direct support for enum fields?
Any way to map a string column to enum during</div>
<div>a ogr2ogr call?</div>
<div><br>
