When dealing with foreign tables, I believe planning is not the same
because of access to statistics (maybe has improved since 9.6 though). I
just wonder... Would it be a viable option to create a materialized view
using the FDW but then use the PHP script against the local tables only?

Best guess is there is no data in table.
Do:
select count(*) from boundaryline.scotland_and_wales_const_region;
Any way to visualise?

Add semi-colon return?

You need to rethink. The datatype input function cannot know even that
the value is going to be stored

Hi Laurenz,
I need the page and possibly row of the data location to be stored as an
element of the new type. This is to simulate a structure from another database
system.

Hello everyone.
I got here after encountering the same difficulty, although on a much more
mundane scenario.
I'm used to fdw on a read-only basis. I was just inserting a new record on
a foreign table and got blocked... and after much searching got here.
Not to rant or anything, but I am

Thanks David for the reply, but my question was a little different.

Why do I need to execute the CTE query twice

Hi,
Can I have multiple select statements using one WITH statement?
WITH t AS (
Select A, B from ...
)
SELECT A into tableA FROM t where ;
SELECT B into tableB FROM t where ;
