    <title>topic Does ArcMap support PostGIS spatial datatypes with curves (CURVEPOLYGON and MULTISURFACE)? in ArcMap Questions</title>

    <description>&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;I have a PostGIS DB with tables with geometries of datatypes CURVEPOLYGON or MULTISURFACE that I try to read (not edit) in ArcMap or ArcGIS Pro&amp;nbsp; (in QGIS it just works fine). I'm using ArcMap 10.8/ArcGIS Pro 2.5.0/PostgreSQL 14.0/PostGIS 3.1. I'm connecting directly (no SDE involved)&lt;/P&gt;&lt;P&gt;Does ArcMap (and ArcGIS Pro) support curves, i.e. datatype CURVEPOLYGON and MULTISURFACE ?&lt;/P&gt;&lt;P&gt;Documentation (&lt;A href="https://desktop.arcgis.com/en/arcmap/latest/manage-data/gdbs-in-postgresql/data-types-postgresql.htm" target="_blank"&gt;https://desktop.arcgis.com/en/arcmap/latest/manage-data/gdbs-in-postgresql/data-types-postgresql.htm&lt;/A&gt;) just says that it supports "Geometry (PostGIS)" in general. But does that mean it supports all subtypes of type "geometry" ?&lt;/P&gt;&lt;P&gt;While it works fine with objects of datatype "MULTIPOLYGON", nothing is displayed for objects of datatype "CURVEPOLYGON" and opening the attribute table fails with the error message:&lt;/P&gt;&lt;BLOCKQUOTE&gt;&lt;P&gt;"Error reading OID from table.....Invalid Entity type. the operation is not supported by this implementation"&lt;/P&gt;&lt;/BLOCKQUOTE&gt;&lt;P&gt;My definition of OID is the same in both cases: id integer NOT NULL,&lt;/P&gt;&lt;P&gt;A hint that curves are not supported is the drop-down list "Geometry Type" in the "New Query Layer" window that only offers "Polygon".&lt;/P&gt;&lt;P&gt;When trying with ArcGIS Pro I get the following error message when I try to add the data to the map:&lt;/P&gt;&lt;BLOCKQUOTE&gt;&lt;P&gt;Exception from HRESULT: 0x80041520&lt;/P&gt;&lt;/BLOCKQUOTE&gt;&lt;P&gt;Can anybody confirm that PostGIS curved datatypes are NOT supported by ArcMap and ArcGIS Pro ?&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;</description>
