upgrade from 18beta1 to 18beta3 gives : FATAL: database files are incompatible with server

Hi for the sake of answering here : https://www.postgresql.org/message-id/48a32f45-57f2-4560-ae94-3488b3568c8a%40cloud.gatewaynet.com (although I didn't find anything indicating any hope for any change regarding my deadlock), it seems I am unable to binary upgrade from 18beta1 to 18beta3 the traditional easy way between minor releases. After : make install , it gives

Examine the log output.

Is the catalog version indeed different between 18beta1 and 18beta3 ?
