The idea was to generate all the junk in a destroyable subcontext rather than leaking it in the caller's context, but partition_bounds_create was still being called in the caller's context, allowing plenty of scope for leakage. Also, get_rel_relkind() was still being called in the rel's rd_pdcxt, creating a risk of session-lifespan memory wastage. Simplify the logic a bit while at it. Also, reduce rd_pdcxt to ALLOCSET_SMALL_SIZES, since it seems likely to not usually be big. Probably something like this needs to be back-patched into v11, but for now let's get some buildfarm testing on this. Discussion: https://postgr.es/m/15943.1552601288@sss.pgh.pa.us |
