DynamicPageList3 ver 3.3.2 (5157453, 19 sep 2018) is generating SQL in a few places which is not accepted by 10.1.38-MariaDB-0ubuntu0.18.04.1
This is either faulty or incompatible SQL syntax.
This DPL query from https://desencyclopedie.org/wiki/Cat%C3%A9gorie:BestOf fails:

Function: Wikimedia\Rdbms\Database::query
Error: 1052 Column 'rev_minor_edit' in where clause is ambiguous (localhost)Neither of these are invalid DPL queries; the faulty SQL could be fixed by removing COLLATION 'latin1_swedish_ci' from the SQL in the first query and changing "rev_minor_edit" to "rev.rev_minor_edit" in the second query. That would involve a pair of relatively minor changes to the DPL3 source code - just search the code for these queries and fix them.
While there are other, more serious issues with every version of DPL (Intersection, DPL2, DPL3) such as T124841 the syntactically-flawed SQL queries are low-hanging fruit which should be picked off?
