Probably wrong destination is selected:

fiware-cygnus/cygnus-common/src/main/java/com/telefonica/iot/cygnus/backends/sql/SQLBackendImpl.java

Line 943 in 269af1d

jdbcUrl = "jdbc:" + sqlInstance + "://" + sqlHost + ":" + sqlPort + "/" + defaultSQLDataBase;

postgresql/postgis is using destination for schemaname and dbname, but both should be spltited and propagated from https://github.com/telefonicaid/fiware-cygnus/blob/master/cygnus-ngsi/src/main/java/com/telefonica/iot/cygnus/sinks/NGSIPostgisSink.java#L432

Logs should print all dbname, schema, tablename
