for the "postgresql JSON function that wants to be in the FROM clause",
there is a way to do this with plain Core API but it generates a
subquery (that's here:
http://docs.sqlalchemy.org/en/rel_1_0/core/tutorial.html#functions ,
scroll down a little in that section), but also I've been pointing
people to an interim solution that has all of PG's functions in mind,
that is here:
https://bitbucket.org/zzzeek/sqlalchemy/issues/3566/figure-out-how-to-support-all-of-pgs#comment-22842678
. It includes two examples to get you started.

I'm stuck with the need to generate a query of the form like:

SELECT
a.id,
b.name,
jr.*
FROM
a,b outer join jsonb_populate_recordset(b.jrs)asjr(bid numeric,name
varchar)on (TRUE)
WHERE
a.id =b.a_id

First, it's not clear to me how to construct a dynamically defined
RECORD as 'jr(bid numeric, name varchar)' so 'jr' becomes a table name
that could be referenced later on
Then it's not clear to me how to construct a table-like object of a
function call that one can reference in query() by it's name ('jr' in
this case).
Is it possible with SQLAlchemy?
