autoddl: keep an extension's cleanup DDL node-local - #590
Conversation
An extension may run DDL of its own while it is being dropped -- lolor registers a ddl_command_start event trigger whose SPI call renames the native large object functions back into place. With spock.allow_ddl_from_functions on, those ~40 statements were queued for replication. Every peer runs its own copy when it applies the DROP EXTENSION, so the shipped renames land first, leave lolor disabled out of band, and the drop that follows then fails in migrate_to_native() with "lolor must be enabled before migration to native", stalling apply. Core exposes creating_extension, which covers CREATE EXTENSION and ALTER EXTENSION ... UPDATE, but has no counterpart for DROP. Track that half in spock_ProcessUtility() and have autoddl_can_proceed() skip anything nested inside it. The DROP EXTENSION itself is unaffected -- it returns at the toplevel check -- so peers still drop the extension and run their own cleanup. Covered two ways: 034 exercises the guard generally with a synthetic event trigger and no lolor, 033 covers the lolor path end to end across the three-node mesh.

Poem
Merge Risk: 🔵 Low · up to The change keeps extension cleanup DDL local while still replicating the DROP EXTENSION itself, reducing the risk of apply failures across peers. One test assertion should be tightened to require the exact expected queue count because the current check can pass on query failure or duplicate rows; the PR is otherwise mergeable with this follow-up. 🚥 Pre-merge checks | ✅ 4 | ❌ 1❌ Failed checks (1 warning)

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Make the DROP EXTENSION queue assertion strict.
isnt($count, '0') passes for any value other than the string 0. If scalar_query returns undef because the query failed, the test still passes. It also hides a duplicate queue entry. Assert the exact expected count instead, as test 034 does at line 243.

Basically, looks good.
One issue to discuss:
What if the extension is removed implicitly by DROP SCHEMA ... CASCADE, DROP OWNED BY, ... commands? In this case this guard doesn't work.
