JOIN of a table and sub-query containing DISTINCT and table function of a procedural call with arguments fails

1. Create "test_x" and "test_y" tables in a PostgreSQL DB: CREATE TABLE public .test_x ( b boolean ); INSERT INTO public .test_x( b) VALUES ( true ); CREATE TABLE public .test_y ( i integer ); INSERT INTO public .test_y( i) VALUES (2); 2. Add postgresql (in my example I use "test" database) database configurations in standalone-teiid.xml: <datasource jndi-name= "java:/test_tables_pg" pool-name= "test_tables_pg" enabled= "true" use-java-context= "true" > <connection-url> jdbc:postgresql://localhost:5432/test?charSet=utf8 </connection-url> <driver-class> org.postgresql.Driver </driver-class> <driver> org.postgresql </driver> <pool> <min-pool-size> 2 </min-pool-size> <max-pool-size> 70 </max-pool-size> <prefill> false </prefill> <use-strict-min> false </use-strict-min> <flush-strategy> FailingConnectionOnly </flush-strategy> </pool> <security> <user-name> postgres </user-name> <password> xxxxxx </password> </security> <validation> <check-valid-connection-sql> select 0 </check-valid-connection-sql> </validation> <timeout> <blocking-timeout-millis> 120000 </blocking-timeout-millis> <idle-timeout-minutes> 5 </idle-timeout-minutes> </timeout> </datasource> 3. Add in test-vdb.xml java:/test_tables_pg configured in previous step as data source: <model name= "test_tables_pg" > <property name= "importer.useFullSchemaName" value= "false" /> <property name= "importer.tableTypes" value= "TABLE,VIEW" /> <property name= "importer.importKeys" value= "false" /> <source name= "test_tables_pg" translator-name= "myPg" connection-jndi-name= "java:/test_tables_pg" /> </model> <translator name= "myPg" type= "postgresql" > <property name= "SupportsNativeQueries" value= "true" /> </translator> 4. Add in test-vdb.xml the virtual "pr" procedure: <model visible = "true" type = "VIRTUAL" name = "views" > <metadata type = "DDL" > <![CDATA[ CREATE PROCEDURE pr(arg string) RETURNS (res integer) AS BEGIN SELECT 2; END ]]> </metadata> </model> 5. Comment out Unable to find source-code formatter for language: noformat.

Run the following query: SELECT t2.i FROM ( SELECT DISTINCT 1 a , b from test_tables_pg.test_x) t1, table ( CALL "views.pr" (arg => t1. a ) ) sub JOIN test_tables_pg.test_y t2 ON true ;; A note: if you allow to add the Limit clause automatically in Request.generatePlan method then the query above won't fail.
