GeoServer code almost never knows about the nature of the underlying
storage, it uses the GeoTools API
to access data, in this case, it's using a UniqueVisitor if possible (or a
min/max one depending on the representation type):
https://github.com/geoserver/geoserver/blob/master/src/wms/src/main/java/org/geoserver/wms/WMS.java#L947
This in turn should lead to the encoding of a aggregate function here:
https://github.com/geotools/geotools/blob/master/modules/library/jdbc/src/main/java/org/geotools/jdbc/JDBCDataStore.java#L1279
However, there might be some hiccups in the intermediary classes between
the first and the second code bits,
maybe a wrapper that does reprojection, crs forcing or something like that
misses the appropriate delegation.
Which is actually something Justin (cc'ed) tried to fix some time ago, but
not sure in which branch that work landed?
It might be that 2.4 beta does not exhibit this problem anymore.
Cheers
Andrea
