describeOneTableDetails issued a partition-constraint-fetching query for every table, even ones it knows perfectly well are not partitions. To add insult to injury, it then proceeded to leak the empty PGresult if the table wasn't a partition. Doing that a lot of times might amount to a meaningful leak, so this seems like a back-patchable bug. Fix that, and also fix a related PGresult leak in the partition-parent case (though that leak would occur only if we got no row, which is unexpected). Minor code beautification too, to make this code look more like the pre-existing code around it. Back-patch the whole change into v12. However, the fact that we already know whether the table is a partition dates only to commit 1af25ca0c; back-patching the relevant changes from that is probably more churn than is justified in released branches. Hence, in v11 and v10, just do the minimum to fix the PGresult leaks. Noted while messing around with adjacent code for yesterday's \d improvements. |
