Explicitly track whether aggregate final functions modify transition state.
Up to now, there's been hard-wired assumptions that normal aggregates'
final functions never modify their transition states, while ordered-set
aggregates' final functions always do. This has always been a bit
limiting, and in particular it's getting in the way of improving the
built-in ordered-set aggregates to allow merging of transition states.
Therefore, let's introduce catalog and CREATE AGGREGATE infrastructure
that lets the finalfn's behavior be declared explicitly.
There are now three possibilities for the finalfn behavior: it's purely
read-only, it trashes the transition state irrecoverably, or it changes
the state in such a way that no more transfn calls are possible but the
state can still be passed to other, compatible finalfns. There are no
examples of this third case today, but we'll shortly make the built-in
OSAs act like that.
This change allows user-defined aggregates to explicitly disclaim support
for use as window functions, and/or to prevent transition state merging,
if their implementations cannot handle that. While it was previously
possible to handle the window case with a run-time error check, there was
not any way to prevent transition state merging, which in retrospect is
something commit 804163bc2 should have provided for. But better late
than never.
In passing, split out pg_aggregate.c's extern function declarations into
a new header file pg_aggregate_fn.h, similarly to what we've done for
some other catalog headers, so that pg_aggregate.h itself can be safe
for frontend files to include. This lets pg_dump use the symbolic
names for relevant constants.

Ordinarily, Postgres functions are expected to be true functions that
|
||||
do not modify their input values. However, an aggregate transition
|
||||
function, <emphasis>when used in the context of an aggregate</>,
|
||||
is allowed to cheat and modify its transition-state argument in place.

This can provide substantial performance benefits compared to making

<para>
|

Likewise, while an aggregate final function is normally expected not to
|
||||
modify its input values, sometimes it is impractical to avoid modifying
|
||||
the transition-state argument. Such behavior must be declared using
|
||||
the <literal>FINALFUNC_MODIFY</> parameter. The <literal>READ_WRITE</>
|
||||
value indicates that the final function modifies the transition state in
|
||||
unspecified ways. This value prevents use of the aggregate as a window
|
||||
function, and it also prevents merging of transition states for aggregate
|
||||
calls that share the same input values and transition functions.
|
||||
The <literal>SHARABLE</> value indicates that the transition function
|
||||
cannot be applied after the final function, but multiple final-function
|
||||
calls can be performed on the ending transition state value. This value
|
||||
prevents use of the aggregate as a window function, but it allows merging
|
||||
of transition states. (That is, the optimization of interest here is not
|
||||
applying the same final function repeatedly, but applying different final
|
||||
functions to the same ending transition state value. This is allowed as
|
||||
long as none of the final functions are marked <literal>READ_WRITE</>.)
