Hstore OID bigger than an integer

Hello team,

This is the first time I post here, if you can provide some help, would be
much appreciated.

I have an application that can not access the database due to OID value for
hstore extension is bigger than an integer value. Application uses a NpgSql
driver that only supports integer types for OIDs.

We have a new app version, which uses a new driver version that supports
bigint and has no issues at all, but for that specific database, we still
need to use that old version of the app.

I have searched for a workaround or something that can help us to be able
to connect to the database, but have not found anything related.

I also tried by dropping, creating extension again, but same result.

Does any of you know any workaround that can help here?

We are using postgresql 9.2.24.

Thanks.
