When running a recursive common table expression query against a source that does not support recursive cte pushdown, only the recursive part of the query is pushed, which fails, since it references a non-existent table (the cte). E. g. the query WITH tmp_cte(id, fk, lvl) AS ( SELECT id, fk, 0 as lvl FROM SourceModel.cte_source WHERE fk IS NULL UNION ALL SELECT e.id, e.fk, lvl + 1 as lvl FROM SourceModel.cte_source AS e INNER JOIN tmp_cte AS ecte ON ecte.id = e.fk ) SELECT * FROM tmp_cte against a PostreSQL source results in Remote org.postgresql.util.PSQLException: ERROR: relation "tmp_cte" does not exist because this query is pushed down: SELECT g_0.id, g_0.fk, g_0.lvl FROM tmp_cte AS g_0
