I think this doubles down on bad design in the logical replication code,
or at least it goes against what we do almost everywhere else in backend
code. We should do less freeing, more context deleting/resetting.
(Storing stuff in CacheMemoryContext was surely a mistake.)
If you don't like the idea of a static memcxt in the one block where
it's needed, I propose to store a new memcxt in PGOutputData, to be used
exclusively for publications, with a well defined lifetime. I'm against
reusing data->cachecxt, because the lifetime of that is 100% unclear.
