This code is unsafe, as proven by buildfarm failures, because it tries to access shared memory that might already be gone. It's also unnecessary, because we're about to exit the process anyway and so the record type cache should never be accessed again. The idea was to lay some foundations for someday recycling workers --- which would require attaching to a different shared tupdesc registry --- but that will require considerably more thought. In the meantime let's save some bytes by just removing the nonfunctional code. Problem identification, and proposal to fix by removing functionality from the detach function, by Thomas Munro. I went a bit further by removing the function altogether. Discussion: https://postgr.es/m/E1dsguX-00056N-9x@gemulon.postgresql.org |
