Get rid of old version of BuildTupleHashTable().
It was reasonable to preserve the old API of BuildTupleHashTable()
in the back branches, but in HEAD we should actively discourage use
of that version. There are no remaining callers in core, so just
get rid of it. Then rename BuildTupleHashTableE
Use ExecGetCommonSlotOps infrastructure in more places.
Append, MergeAppend, and RecursiveUnion can all use the support
functions added in commit 276279295. The first two can report a
fixed result slot type if all their children return the same fixed
slot type. That does nothing for the append s
Convert SetOp to read its inputs as outerPlan and innerPlan.
The original design for set operations involved appending the two
input relations into one and adding a flag column that allows
distinguishing which side each row came from. Then the SetOp node
pries them apart again based on the flag.
Improve planner's handling of SetOp plans.
Remove the code for inserting flag columns in the inputs of a SetOp.
That was the only reason why there would be resjunk columns in a
set-operations plan tree, so we can get rid of some code that
supported that, too.
Get rid of choose_hashed_setop() in f
Fix bitmap table scan crash on iterator release
1a0da347a7ac98db replaced Bitmap Table Scan's individual private and
shared iterators with a unified iterator. It neglected, however, to
check if the iterator had already been cleaned up before doing so on
rescan. Add this check both on rescan and en
Remove extra prefetch iterator setup for Bitmap Table Scan
1a0da347a7ac98db replaced Bitmap Table Scan's separate private and
shared bitmap iterators with a unified iterator. It accidentally set up
the prefetch iterator twice for non-parallel bitmap table scans. Remove
the extra set up call to tbm

bootstrap: pure parser and reentrant scanner
Use the flex %option reentrant and the bison option %pure-parser to
make the generated scanner and parser pure, reentrant, and
thread-safe.
Make the generated scanner use palloc() etc. instead of malloc() etc.
For the bootstrap scanner and parser, ree

Prevent redeclaration of typedef yyscan_t
Fix for 1f0de66ea2a: We need to prevent redeclaration of typedef
yyscan_t. (This will work with C11 but not currently with C99.) The
generated scanner files provide their own typedef, but we also need to
provide one for the interfaces that we expose. So
