Boolean expression is incorrectly rewritten in WHERE condition and causes errors on PG

1. In PostgreSQL create the test_bool_exps table by the following script: CREATE TABLE public .test_bool_exps ( a integer , b boolean ); INSERT INTO public .test_bool_exps( a , b) VALUES (1, true ); 2. Add PostgreSQL database configuration in standalone-teiid.xml: <datasource jndi-name= "java:/test_pg" pool-name= "test_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 test_pg model configured in previous step as datasource: <model name= "test_pg" > <property name= "importer.useFullSchemaName" value= "false" /> <property name= "importer.tableTypes" value= "TABLE,VIEW" /> <property name= "importer.importKeys" value= "false" /> <source name= "test_pg" translator-name= "postgresql" connection-jndi-name= "java:/test_pg" /> </model> 4. run the following query: select * from test_pg.test_bool_exps where ((b= true ) and ( a =1)) = true ;;
