Base files compatibility between PG11 and PG15

Hi,

I have a database on Aurora@RDS.
It Used  V11.9, and then upgraded automatically by AWS to V15.2 AWS states that it relies on compatibility provided by
thePG community. 
We now experience problems with the data.
Has anyone met similar issues? Compatibility of data files?

Thanks

Danny

The data-files are nowhere near compatible between major-versions, as stated clearly in all release notes:

https://www.postgresql.org/docs/release/12.0/

https://www.postgresql.org/docs/release/13.0/

https://www.postgresql.org/docs/release/14.0/

https://www.postgresql.org/docs/release/15.0/

 

They all state the same:

“A dump/restore using pg_dumpall or use of pg_upgrade or logical replication is required for those wishing to migrate data from any previous release.”

This needs more information:

1) Describe the upgrade process

2) Describe the data problems.

Plus it is Aurora, which is not community Postgres.
