PyObject returned from PySequence_GetItem() is not released. Similar code in PLyMapping_ToJsonbValue() is correct, because according to Python documentation
PyList_GetItem() and PyTuple_GetItem() return a borrowed reference while
PySequence_GetItem() returns new reference. contrib/jsonb_plpython is new
in PostgreSQL 11, no backpatch is needed.

As in e348e7ae57 for jsonb/plperl, prevent
putting a NaN into a jsonb numeric field.
Tests for this had been removed in
6278a2a262, but in case they are ever
resurrected: This would change the output of the test1nan() function to
an error.
Failure to use DatumGetFoo/FooGetDatum macros correctly, or at all,
causes some warnings about sign conversion. This is just cosmetic
at the moment but in principle it's a type violation, so clean up
the instances I could find.
autoprewarm.c and sharedfileset.c contained code that unportably
assumed that pid_t is the same size as int. We've variously dealt
with this by casting pid_t to int or to unsigned long for printing
purposes; I went with the latter.
Fix uninitialized-variable warning in RestoreGUCState. This is
a live bug in some sense, but of no great significance given that
nobody is very likely to care what "line number" is associated with
a GUC that hasn't got a source file recorded.
Add a new contrib module jsonb_plpython that provide a transform between
jsonb and PL/Python. jsonb values are converted to appropriate Python
types such as dicts and lists, and vice versa.
