I don’t think geoserver's behaviour is correct, so maybe it's worth logging an issue.
I've also wondered why they don't simply use SELECT COUNT(*) and don't mention the column names. The code would be much simpler and always correct independent of the number of columns. It might return a different number if the ID is not unique or null, but then you don't really have an ID, so that's probably not a problem.

But it resulted in the offensive database-query. I removed the concatenation (and moved it to the features-templating) and everything works fine.

It seems to fix situations where there are 0 ID columns, but breaks everything where there are >1 ID columns. Your error talks about 3 ID columns, so you are impacted.

Activating "NumberMatched skip" as a workaround is successful under geosever 2.21.2 2. Julian: the WFS query is http://localhost:8080/geoserver/eposgo/ows?service=WFS&version=1.0.0&request=GetFeature&typeName=eposgo%3AMagnetotelluricStationsFeature&maxFeatures=5&outputFormat=application%2Fjson (this is copied from the layer preview and any format will generate the error; same if I remove maxFeatures) 3. Although I have never touched "NumberMatched skip" before, I checked the setting under geoserver 2.21.1, and it is as expected deactivated. Thus, * the query above under geoserver 2.21.1 works totally fine * the query above under geoserver 2.21.2 works only with "NumberMatched skip" activated I have now a workaround and will try to follow up according to Hans's suggestion. But this still leaves two open questions: 1. Why has the behaviour of geoserver changed from 2.21.1 to 2.21.2? 2. Did the change introduce a bug, or is this expected behaviour? (which would mean that the query worked under 2.21.1 because of a bug that was eliminated in 2.21.2) Best wishes, Henning On 2022-11-17 15:14, Hans Yperman wrote: I'll add my 2 cents. The problem is not with the driver, but with the query generated by geoserver: This text: ERROR: function count(character varying, character varying, character varying) does not exist Hint: No function matches the given name and argument types. You might need to add explicit type casts. Position: 8 is an SQL error message from postgres. The postgres jdbc driver is just the transport of this message, not the cause. The SQL is generated by at org.geotools.appschema.jdbc.JoiningJDBCFeatureSource.getCountInternal(JoiningJDBCFeatureSource.java:1523) so let's look at that file:https://github.com/geotools/geotools/blob/main/modules/extension/app-schema/app-schema/src/main/java/org/geotools/appschema/jdbc/JoiningJDBCFeatureSource.java#L1523 The query comes from either createCountQuery or createJoiningCountQuery, and both generate a query with this shape: SELECT COUNT(DISTINCT idcolumn,idcolumn,…) FROM (…) Notice how COUNT is on position 8 in this query, which matches the error message. The error also claims there are 3 arguments given to count. Now, 3 args seems strange: AFAIK the count syntax accepts only 1 column. If there are multiple ID columns, geoserver does something I can't help you with. Next steps could be: 1) Try to get hold of the actual query, e.g. grab it from the network with wireshark, log it on the postgres server, put a java breakpoint on that line 1523, … 2) Once you have it, run it on your database with pgadmin or psql or … . Validate you get the same error message. Play with it until the error goes away. 3) Convince geoserver to generate a valid query based on whatever you learned from 2). I'd guess this would do something with the id columns. There might be a workaround: Under Layer settings > Publish, there is a setting that lets you skip the NumberMatched counting. If you can live without this count, you can hide the problem by enabling that setting.
