PostgreSqlFeatureSource does not correctly quote feature ID column

(ThinkGeo.UI.Wpf 12.1.3, ThinkGeo.PostgreSql 12.1.3)

When I try to show a layer that has uppercase column names:

var layer = new PostgreSqlFeatureLayer("Host=localhost;Username=postgres", "mm_tr_sm",
                                       "MI_PRINX", 28992, "testprj", "GEOLOC");

then I get just an error message in the map:

The server’s log shows that the feature ID column name is not quoted:

 ERROR:  column "mi_prinx" does not exist at character 42
 STATEMENT:  select st_asbinary("GEOLOC") as "GEOLOC",MI_PRINX from "testprj"."mm_tr_sm" where ST_GeomFromWKB($1,28992) && "GEOLOC"

If I try to add quotes to the string, the map display itself works, but other functions that do quote correctly blow up:

var layer = new PostgreSqlFeatureLayer("Host=localhost;Username=postgres", "mm_tr_sm",
                                       "\"MI_PRINX\"", 28992, "testprj", "GEOLOC");
layer.Open();
layer.FeatureSource.GetBoundingBoxById("1");
 ERROR:  zero-length delimited identifier at or near """" at character 85
 STATEMENT:  select st_asbinary("GEOLOC") as "GEOLOC","MI_PRINX" from "testprj"."mm_tr_sm" where ""MI_PRINX"" in ('1')

Hi Clemens,

Thank you very much for report this issue, it’s proved to be a bug in SDK, it has been fixed in the latest develop branch, in other words, you can try update ThinkGeo.PostgreSql to version higher or equal to 13.0.0-beta043 to get it fixed. After this fix applied, don’t need to add “quotes” to the string, just keep the code of creating instance as following:

var layer = new PostgreSqlFeatureLayer("Host=localhost;Username=postgres", "mm_tr_sm",
                                       "MI_PRINX", 28992, "testprj", "GEOLOC");

please take a try at first, if everything goes well on your side, I will talk with guys to see if it can be merged into master branch later.

Regards,
Johnny

beta043 works fine.
Thanks!
