I was investigating the following crash where a checkpoint task had its underlying resources being destroyed while it was still running.

have been scheduled but before `checkpoint_state.executor.WorkOnTasks();` is called, it results in an InternalException / DuckDB crash as the `Checkpoint ` method does not wait for the scheduled tasks to have completed before destroying the referenced resources.

Fixes duckdblabs/duckdb-internal#3922 The failing query ```SQL SET order_by_non_integer_literal=true; SELECT DISTINCT ON ( 'string' ) 'string', GROUP BY CUBE ( 'string', ), 'string' IN ( SELECT 'string' ), HAVING 'string' IN ( SELECT 'string'); ``` The Plan generated before optimization is below. During optimization there is an attempt to convert the mark join into a semi. Before this conversion takes place, we usually check to make sure the mark join is not used in any operators above the mark join to prevent plan verification errors. Up until this point, only logical projections were checked for mark joins. Turns out this query is planned in such a way that the mark join is in one of the expressions of the aggregate operator. This was not checked, so the mark to semi conversion would take place. The fix is to modify the filter pushdown optimization so that it stores table indexes from logical aggregate operators. ``` ┌───────────────────────────┐ │ PROJECTION #1 │ │ ──────────────────── │ │ Expressions: #[2.0] │ └─────────────┬─────────────┘ ┌─────────────┴─────────────┐ │ FILTER │ │ ──────────────────── │ │ Expressions: #[2.1] │ └─────────────┬─────────────┘ ┌─────────────┴─────────────┐ │ AGGREGATE #2, #3, #4 │ │ ──────────────────── │ │ Groups: │ │ 'string' │ │ #[14.0] │ └─────────────┬─────────────┘ ┌─────────────┴─────────────┐ │ COMPARISON_JOIN │ │ ──────────────────── │ │ Join Type: MARK │ │ ├──────────────┐ │ Conditions: │ │ │ ('string' = #[8.0]) │ │ └─────────────┬─────────────┘ │ ┌─────────────┴─────────────┐┌─────────────┴─────────────┐ │ DUMMY_SCAN #0 ││ PROJECTION #8 │ │ ──────────────────── ││ ──────────────────── │ │ ││ Expressions: 'string' │ └───────────────────────────┘└─────────────┬─────────────┘ ┌─────────────┴─────────────┐ │ DUMMY_SCAN #7 │ │ ──────────────────── │ └───────────────────────────┘ ```

```
Core dump analysis showed that the assertion `D_ASSERT(lstate.writer);`
in `MergeCollectionTask::Execute` (i.e. it is crashing because
`lstate.writer` is NULLPTR) was not satisfied when
`PhysicalBatchInsert::Sink` was processing merge tasks from (other)
pipeline executors.
My suspicion is that this is only likely to happen for heavily
concurrent workloads (applicable to the two users which crashed). The
patch submitted as part of this PR has addressed the issue for these
users.

I have seen this crashing due to invalid pointer on which a destructor is called, on last night `main` (`2ed9bf887f`) using unittester compiled from sources (clang 17) and extensions installed from default extension repository. Basically: ``` DYLD_INSERT_LIBRARIES=/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/lib/clang/17/lib/darwin/libclang_rt.asan_osx_dynamic.dylib LOCAL_EXTENSION_REPO=http://extensions.duckdb.org ./build/release/test/unittest --autoloading all --skip-compiled --order rand test/parquet/test_parquet_schema.test ``` and seeing runtime sanitizer assertions such as ``` ==56046==ERROR: AddressSanitizer: container-overflow on address 0x6100000d4dcf at pc 0x000116c7f450 bp 0x00016fc1d170 sp 0x00016fc1d168 READ of size 1 at 0x6100000d4dcf thread T0 #0 0x000116c7f44c in std::__1::basic_string<char, std::__1::char_traits<char>, std::__1::allocator<char>>* std::__1::__uninitialized_allocator_copy_impl[abi:ne190102]<std::__1::allocator<std::__1::basic_string<char, std::__1::char_traits<char>, std::__1::allocator<char>>>, std::__1::basic_string<char, std::__1::char_traits<char>, std::__1::allocator<char>>*, std::__1::basic_string<char, std::__1::char_traits<char>, std::__1::allocator<char>>*, std::__1::basic_string<char, std::__1::char_traits<char>, std::__1::allocator<char>>*>(std::__1::allocator<std::__1::basic_string<char, std::__1::char_traits<char>, std::__1::allocator<char>>>&, std::__1::basic_string<char, std::__1::char_traits<char>, std::__1::allocator<char>>*, std::__1::basic_string<char, std::__1::char_traits<char>, std::__1::allocator<char>>*, std::__1::basic_string<char, std::__1::char_traits<char>, std::__1::allocator<char>>*)+0x318 (parquet.duckdb_extension:arm64+0xab44c) #1 0x000116c7ec90 in void std::__1::vector<std::__1::basic_string<char, std::__1::char_traits<char>, std::__1::allocator<char>>, std::__1::allocator<std::__1::basic_string<char, std::__1::char_traits<char>, std::__1::allocator<char>>>>::__construct_at_end<std::__1::basic_string<char, std::__1::char_traits<char>, std::__1::allocator<char>>*, std::__1::basic_string<char, std::__1::char_traits<char>, std::__1::allocator<char>>*>(std::__1::basic_string<char, std::__1::char_traits<char>, std::__1::allocator<char>>*, std::__1::basic_string<char, std::__1::char_traits<char>, std::__1::allocator<char>>*, unsigned long)+0x160 (parquet.duckdb_extension:arm64+0xaac90) #2 0x000116c7e7d8 in void std::__1::vector<std::__1::basic_string<char, std::__1::char_traits<char>, std::__1::allocator<char>>, std::__1::allocator<std::__1::basic_string<char, std::__1::char_traits<char>, std::__1::allocator<char>>>>::__assign_with_size[abi:ne190102]<std::__1::basic_string<char, std::__1::char_traits<char>, std::__1::allocator<char>>*, std::__1::basic_string<char, std::__1::char_traits<char>, std::__1::allocator<char>>*>(std::__1::basic_string<char, std::__1::char_traits<char>, std::__1::allocator<char>>*, std::__1::basic_string<char, std::__1::char_traits<char>, std::__1::allocator<char>>*, long)+0x1e0 (parquet.duckdb_extension:arm64+0xaa7d8) #3 0x000116e8cd48 in duckdb::ParquetMultiFileInfo::BindReader(duckdb::ClientContext&, duckdb::vector<duckdb::LogicalType, true>&, duckdb::vector<std::__1::basic_string<char, std::__1::char_traits<char>, std::__1::allocator<char>>, true>&, duckdb::MultiFileBindData&)+0xf18 (parquet.duckdb_extension:arm64+0x2b8d48) #4 0x000116e6e5fc in duckdb::MultiFileFunction<duckdb::ParquetMultiFileInfo>::MultiFileBindInternal(duckdb::ClientContext&, duckdb::unique_ptr<duckdb::MultiFileReader, std::__1::default_delete<duckdb::MultiFileReader>, true>, duckdb::shared_ptr<duckdb::MultiFileList, true>, duckdb::vector<duckdb::LogicalType, true>&, duckdb::vector<std::__1::basic_string<char, std::__1::char_traits<char>, std::__1::allocator<char>>, true>&, duckdb::MultiFileOptions, duckdb::unique_ptr<duckdb::BaseFileReaderOptions, std::__1::default_delete<duckdb::BaseFileReaderOptions>, true>, duckdb::unique_ptr<duckdb::MultiFileReaderInterface, std::__1::default_delete<duckdb::MultiFileReaderInterface>, true>)+0x1210 (parquet.duckdb_extension:arm64+0x29a5fc) ``` or these failures while using ducklake ``` ==56079==ERROR: AddressSanitizer: container-overflow on address 0x616000091a78 at pc 0x0001323fc81c bp 0x00016bd0e890 sp 0x00016bd0e888 READ of size 8 at 0x616000091a78 thread T2049 #0 0x0001323fc818 in duckdb::MultiFileColumnDefinition::~MultiFileColumnDefinition()+0x258 (parquet.duckdb_extension:arm64+0x2a4818) #1 0x0001323fb588 in std::__1::vector<duckdb::MultiFileColumnDefinition, std::__1::allocator<duckdb::MultiFileColumnDefinition>>::__destroy_vector::operator()[abi:ne190102]()+0x98 (parquet.duckdb_extension:arm64+0x2a3588) #2 0x0001324a09e4 in duckdb::BaseFileReader::~BaseFileReader()+0x2bc (parquet.duckdb_extension:arm64+0x3489e4) #3 0x0001324a23ec in duckdb::ParquetReader::~ParquetReader()+0x22c (parquet.duckdb_extension:arm64+0x34a3ec) ```

I am not sure if the fix could / should be elsewhere.
