Document workaround for when backup cannot be restored with `pg_stat_statements` enabled
Problem to solve
In #351071 we have investigated why sometimes restoring from a backup fails due to pg_stat_statements
enabled being enabled.
While a more permanent solution or workaround will be implemented in that issue, we should consider adding documentation explaining how to manually workaround the problem in an existing installation.
The documentation would be valid for recovering in any version prior to the one that ships a fix from #351071.
Proposal
There is a large discussion on what the solution should be and some workarounds that can be made into documentation instructions here: #351071 (comment 1056890477)
