Maybe. But I noticed that your patch also moves the line "IgnoreSystemIndexes = true;"
earlier. Why did you make this change?

This could cause initdb to fail with a PANIC error when run with ignore_system_indexes=off,
like this:

     $ initdb -D data -c ignore_system_indexes=off
     ...
     FATAL:  could not open relation with OID 2703
     PANIC:  cannot abort transaction 1, it was already committed

So perhaps "IgnoreSystemIndexes = true;" should be placed after GUCs are processed?
Or GUC ignore_system_indexes also should be treated in the same way
as transaction_timeout?
