Hi, Presently, replication slot invalidation causes and their text are scattered into ReplicationSlotInvalidationCause enum and a bunch of macros. This is making the code to get invalidation cause text given the cause as enum and vice-versa unreadable, longer and inextensible. The attached patch adds a lookup table for all invalidation causes for better readability and extensibility. FWIW, another patch in discussion https://www.postgresql.org/message-id/CALj2ACWgACB4opnbqi=x7hc4aqcgkxolsh1vb+gfidxadqn...@mail.gmail.com adds a couple of other invalidation reasons, this lookup table makes the life easier and code shorter.
