The above is not much to go on. So a list of questions below. Please 
answer them all, thanks:

1) How was the production Postgres installed(EDB, native packages) and 
on what OS?

2) The dev Postgres is the one installed using EDB installer, correct?

3) Define working fine. In other words where you/are you using a backup 
method other then pgBackRest on the production and dev server?

4) When you say single database are you talking about a particular 
database in the Postgres cluster or the entire cluster?

5) Why is pgBackRest essential to this? In other words why not use the 
Postgres pg_dump/pg_restore tools?


As to below, this more then a Perl issue it is a package incompatibility 
issue.
