Change "long" numGroups fields to be Cardinality (i.e., double).
We've been nibbling away at removing uses of "long" for a long time,
since its width is platform-dependent. Here's one more: change the
remaining "long" fields in Plan nodes to Cardinality, since the three
surviving examples all rep
Improve planner's estimates of tuple hash table sizes.
For several types of plan nodes that use TupleHashTables, the
planner estimated the expected size of the table as basically
numEntries * (MAXALIGN(dataWidth) + MAXALIGN(SizeofHeapTupleHeader)).
This is pretty far off, especially for small data
Document nbtree row comparison design.
Add comments explaining when and where it is safe for nbtree to treat
row compare keys as if they were simple scalar inequality keys on the
row's most significant column. This is particularly important within
_bt_advance_array_keys, which deals with required

Remove obsolete nbtree equality key comments.
_bt_first reliably uses the same equality key (on each index column) for
initial positioning purposes as the one that _bt_checkkeys can use to
end the scan following commit f09816a0. _bt_first no longer applies its

Avoid mixing void and integer in a conditional expression.
The C standard says that the second and third arguments of a
conditional operator shall be both void type or both not-void
type. The Windows version of INTERRUPTS_PENDING_CONDITION()
got this wrong. It's pretty harmless because the resul
