Add backend-level statistics to pgstats
This adds a new variable-numbered statistics kind in pgstats, where the
object ID key of the stats entries is based on the proc number of the
backends. This acts as an upper-bound for the number of stats entries
that can exist at once. The entries are crea
Extract logic filling pg_stat_get_io()'s tuplestore into its own routine
This commit adds pg_stat_io_build_tuples(), a helper routine for
pg_stat_get_io(), that fills its result tuplestore based on the contents
of PgStat_BktypeIO. This will be used in a follow-up commit that uses
the same structu
Optimize grouping equality checks with virtual slots
8f4ee9626 fixed an old Assert failure that could happen when the slot
type used to look up the hash table for BuildTupleHashTableExt() users
wasn't a TTSOpsMinimalTuple slot. The fix for that in the back branches
had to be to pass the TupleTabl
Fix Assert failure in WITH RECURSIVE UNION queries
If the non-recursive part of a recursive CTE ended up using
TTSOpsBufferHeapTuple as the table slot type, then a duplicate value
could cause an Assert failure in CheckOpSlotCompatibility() when
checking the hash table for the duplicate value. The

Remove leftover mentions of XLOG_HEAP2_FREEZE_PAGE records
f83d709760d merged the separate XLOG_HEAP2_FREEZE_PAGE records into a
new combined prune, freeze, and vacuum record with opcode

Bitmap Table Scans use unified TBMIterator
With the repurposing of TBMIterator as an interface for both parallel
and serial iteration through TIDBitmaps in commit 7f9d4187e7bab10329cc,
bitmap table scans may now use it.
Modify bitmap table scan code to use the TBMIterator. This requires
moving ar
Add common interface for TBMIterators
Add and use TBMPrivateIterator, which replaces the current TBMIterator
for serial use cases, and repurpose TBMIterator to be a unified
interface for both the serial ("private") and parallel ("shared") TID
Bitmap iterator interfaces. This encapsulation simplifi
Fix overflow danger in SampleHeapTupleVisible()
68d9662be1c4b70 made HeapScanDesc->rs_ntuples unsigned but neglected to
change how it was being used in SampleHeapTupleVisible().
Return early if rs_ntuples is 0 to avoid overflowing and incorrectly
executing the loop code in SampleHeapTupleVisible(

Make rs_cindex and rs_ntuples unsigned
HeapScanDescData.rs_cindex and rs_ntuples can't be less than 0. All scan
types using the heap scan descriptor expect these values to be >= 0.
Make that expectation clear by making rs_cindex and rs_ntuples unsigned.
Also remove the test in heapam_scan_bitmap_
