## Problem Currently our testing environment only supports running a single pageserver at a time. This is insufficient for testing failover and migrations. - Dependency of writing tests for #5207 ## Summary of changes - `neon_local` and `neon_fixture` now handle multiple pageservers - This is a breaking change to the `.neon/config` format: any local environments will need recreating - Existing tests continue to work unchanged: - The default number of pageservers is 1 - `NeonEnv.pageserver` is now a helper property that retrieves the first pageserver if there is only one, else throws. - Pageserver data directories are now at `.neon/pageserver_{n}` where n is 1,2,3... - Compatibility tests get some special casing to migrate neon_local configs: these are not meant to be backward/forward compatible, but they were treated that way by the test.
