Our maintenance of typedefs.list has been a little haphazard
(and apparently we can't alphabetize worth a darn). Replace
the file with the authoritative list from our buildfarm, and
run pgindent using that.
I also updated the additions/exclusions lists in pgindent where
necessary to keep pgindent from messing things up significantly.
Notably, now that regex_t and some related names are macros not real
typedefs, we have to whitelist them explicitly. The exclusions list
has also drifted noticeably, presumably due to changes of system
headers on the buildfarm animals that contribute to the list.
Unlike in prior years, I've not manually added typedef names that
are missing from the buildfarm's list because they are not used to
declare any variables or fields. So there are a few places where
the typedef declaration itself is formatted worse than before,
e.g. typedef enum IoMethod. I could preserve the names that were
manually added to the list previously, but I'd really prefer to find
a less manual way of dealing with these cases. A quick grep finds
about 75 such symbols, most of which have never gotten any special
treatment.
Per discussion among pgsql-release, doing this now seems appropriate
even though we're still a week or two away from making the v18 branch.

plpython.h included plpy_util.h, simply on the grounds that "it's
easier to just include it everywhere". However, plpy_util.h must
include plpython.h, or it won't pass headerscheck. While the
resulting circularity doesn't have any immediate bad effect,
it's poor design. We have seen serious messes arise in the past
from overly-broad inclusion footprints created by such circularities,
so let's establish a project policy against it.
To fix, just replace *.c files' inclusions of plpython.h with
plpy_util.h. They'll pull in plpython.h indirectly; indeed, almost
all have already done so via inclusions of other plpy_xxx.h headers.
(Any extensions using plpython.h can do likewise without breaking
the compatibility of their code with prior Postgres versions.)

Using the Python Limited API would allow building PL/Python against
any Python 3.x version and using another Python 3.x version at run
time. This commit does not activate that, but it prepares the code to
only use APIs supported by the Limited API.
Implementation details:
- Convert static types to heap types
(https://docs.python.org/3/howto/isolating-extensions.html#heap-types).
- Replace PyRun_String() with component functions.
- Replace PyList_SET_ITEM() with PyList_SetItem().
This was previously committed as c47e8df815c and then reverted because
it wasn't working under Python older than 3.8. That has been fixed in
this version. There was a Python API change/bugfix between 3.7 and
3.8 that directly affects this patch. The relevant commit is
<https://github.com/python/cpython/commit/364f0b0f19c>. The
workarounds described there have been applied in this patch, and it
has been confirmed to work with Python 3.6 and 3.7.

This reverts commit c47e8df815c1c45f4e4fc90d5817d67ab088279f.
That commit makes the plpython tests crash with Python 3.6.* and
3.7.*. It will need further investigation and testing, so revert for
now.

Similar to commits 14aec03502, 7e735035f2 and dddf4cdc33, this commit
makes the order of header file inclusion consistent in more places.

This addresses some issues with unnecessary code comments, fixes various
typos in docs and comments, and removes some orphaned structures and

These are just a few particularly egregious cases that were hard to read
and write, and error prone because of many similar adjacent types.

This is more idiomatic style and available as of Python 2.4, which is
our minimum.

The idea behind SPI_push was to allow transitioning back into an
"unconnected" state when a SPI-using procedure calls unrelated code that
might or might not invoke SPI. That sounds good, but in practice the only
thing it does for us is to catch cases where a called SPI-using function
forgets to call SPI_connect --- which is a highly improbable failure mode,
since it would be exposed immediately by direct testing of said function.
As against that, we've had multiple bugs induced by forgetting to call
SPI_push/SPI_pop around code that might invoke SPI-using functions; these
are much harder to catch and indeed have gone undetected for years in some
cases. And we've had to band-aid around some problems of this ilk by
introducing conditional push/pop pairs in some places, which really kind
of defeats the purpose altogether; if we can't draw bright lines between
connected and unconnected code, what's the point?
Hence, get rid of SPI_push[_conditional], SPI_pop[_conditional], and the
underlying state variable _SPI_curid. It turns out SPI_restore_connection
can go away too, which is a nice side benefit since it was never more than
a kluge. Provide no-op macros for the deleted functions so as to avoid an
API break for external modules.
A side effect of this removal is that SPI_palloc and allied functions no
longer permit being called when unconnected; they'll throw an error
instead. The apparent usefulness of the previous behavior was a mirage
as well, because it was depended on by only a few places (which I fixed in
preceding commits), and it posed a risk of allocations being unexpectedly
long-lived if someone forgot a SPI_push call.

Previously, plpython was in the habit of allocating a lot of stuff in
TopMemoryContext, and it was very slipshod about making sure that stuff
got cleaned up; in particular, use of TopMemoryContext as fn_mcxt for
function calls represents an unfixable leak, since we generally don't
know what the called function might have allocated in fn_mcxt. This
results in session-lifespan leakage in certain usage scenarios, as for
example in a case reported by Ed Behn back in July.
To fix, get rid of all the retail allocations in TopMemoryContext.
All long-lived allocations are now made in sub-contexts that are
associated with specific objects (either pl/python procedures, or
Python-visible objects such as cursors and plans). We can clean these
up when the associated object is deleted.
I went so far as to get rid of PLy_malloc completely. There were a
couple of places where it could still have been used safely, but on
the whole it was just an invitation to bad coding.

This moves the code around from one huge file into hopefully logical
and more manageable modules. For the most part, the code itself was
not touched, except: PLy_function_handler and PLy_trigger_handler were
renamed to PLy_exec_function and PLy_exec_trigger, because they were
not actually handlers in the PL handler sense, and it makes the naming
more similar to the way PL/pgSQL is organized. The initialization of
the procedure caches was separated into a new function
init_procedure_caches to keep the hash tables private to
plpy_procedures.c.
