Support for Decimal128 BSON type?

[akr8527]

Hi,

It seems that Decimal128 BSON type is not supported.

Thanks!

Thank you, @akr8527 for reporting the same. Yes, the bson type deimal128 is not yet supported. We will see if we can support this in the future.

Is there any update on supporting Decimal128? Does anyone have any workaround that allows you to at least see the data. I tried TEXT and JSON and both returned NULL. Setting to JSONB says cannot convert BSON type to column type. I'm happy to do whatever I need to in a view, just need to somehow see the actual data in some format.

Have you tried with NUMERIC?

[warthenr]

Yes that also returns NULL. If I use __data I can see it in the resulting JSON, but no other column is available. Mongo_fdw_version shows 50501. Get Outlook for Android<https://aka.ms/AAb9ysg>

I did see this #121. Not sure if it might help.
