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.

Make sure that function declarations use names that exactly match the
corresponding names from function definitions in a few places. These
inconsistencies were all introduced relatively recently, after the code
base had parameter name mismatches fixed in bulk (see commits starting
with commits 4274dc22 and 035ce1fe).
pg_bsd_indent still has a couple of similar inconsistencies, which I
(pgeoghegan) have left untouched for now.
Like all earlier commits that cleaned up function parameter names, this
commit was written with help from clang-tidy.

Since 19252e8ec93 we reject Python 2 during build configuration. Now that the
dust on the buildfarm has settled, remove Python 2 specific code, including
the "Python 2/3 porting layer".
The code to detect conflicts between plpython using Python 2 and 3 is not
removed, in case somebody creates an out-of-tree version adding back support
for Python 2.

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

The simple slicing API (sq_slice, sq_ass_slice) has been deprecated
since Python 2.0 and has been removed altogether in Python 3, so remove
those functions from the PLyResult class. Instead, the non-slice
mapping functions mp_subscript and mp_ass_subscript can take slice
objects as an index. Since we just pass the index through to the
underlying list object, we already support that. Test coverage was
already in place.

Python Py*_New() functions can fail and return NULL in out-of-memory
conditions. The previous code handled that inconsistently or not at
all. This change organizes that better. If we are in a function that
is called from Python, we just check for failure and return NULL
ourselves, which will cause any exception information to be passed up.
If we are called from PostgreSQL, we consistently create an "out of
memory" error.

This is a mechanical change in preparation for a later commit that
will change the layout of TupleDesc. Introducing a macro to abstract
the details of where attributes are stored will allow us to change
that in separate step and revise it in future.

It is apparently no longer used after the new slicing support was
implemented (a97207b6908f1d4a7d19b37b818367bb0171039f), so let's

The old way of implementing slicing support by implementing
PySequenceMethods.sq_slice no longer works in Python 3. You now have
to implement PyMappingMethods.mp_subscript. Do this by simply
proxying the call to the wrapped list of result dictionaries.
Consolidate some of the subscripting regression tests.

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.
