New mango M2M is providiing feature to migrate data to postgresql, but it is not working. I tried to change Mango DB, Durby to Postgresql, but it created many problems for me:

First issue When Starting Mango after changing configuration:

Related to DATA column which is of BYTEA datatype.

Second, Mango is diplaying this error while adding datasource,

org.springframework.jdbc.BadSqlGrammarException: PreparedStatementCallback; bad SQL grammar [SELECT dp.id,dp.data,dp.xid,dp.dataSourceId,dp.name,dp.deviceName,dp.enabled,dp.pointFolderId,dp.loggingType,dp.intervalLoggingPeriodType,dp.intervalLoggingPeriod,dp.intervalLoggingType,dp.tolerance,dp.purgeOverride,dp.purgeType,dp.purgePeriod,dp.defaultCacheSize,dp.discardExtremeValues,dp.engineeringUnits,ds.name,ds.xid,ds.dataSourceType FROM dataPoints AS dp join dataSources ds on ds.id = dp.dataSourceId WHERE dp.dataSourceId IN (?) ORDER BY dp.deviceName, dp.name LIMIT ? OFFSET ?]; nested exception is org.postgresql.util.PSQLException: ERROR: operator does not exist: integer = character varying
Hint: No operator matches the given name and argument type(s). You might need to add explicit type casts.

:evil:

Any Help would be appreciated...
