_a_simple() we should dump the variable with arrsize "-1" if
it's part of an outer structure.
The patch attached, includes solutions to both the problems and also a
testcase preproc/pointer_to_struct.pgc. This test is a copy of test
preproc/array_of_struct.pgc with the structure arrays repla

the operation like grouping, sorting, aggregation, as
some sort of relation, we can create paths for each of the relation like we
do (I am heavily borrowing from Tom's idea of pathifying those operations).
We will need much lesser hooks in custom scan node.

OR, other option is when sufficiently large output is encountered (larger
than some predefined value MAX_ROWS or something), psql behaves as if
FETCH_COUNT is set to MAX_ROWS. Documenting this behaviour wouldn't be a
problem and would not be a problem
on access pattern.

In such case, it might be valuable to see if we should play with the

This at least caused the outer reference to be added as parameter, but
again no lateral_relid.
Is there an example query (however impractial query it would be), which can
make the lateral_relids set in RelOptInfo of plain base relation?

Right now it works only for PostgreSQL (but can be extended easily for all

It might be worth to look at the XC planner and pick up pieces of work that
