Here's my question- what's the fastest what to retrieve rows from each
of the child tables after I get results from view_a ?
I don't like using temp tables in Postgres (too much pain in the
past), so first selecting into a temp table which could subsequently
be joined against the child tables isn't appealing to me.
The result set from materialized view_a will never exceed 60 rows, so
I'm thinking about this:
a) LOOP on a SELECT FROM view_a
b) for each record, add the row id to one of 3 comma delimited strings
(one per child table)
c) perform a SELECT WHERE IN (delimited_string) from each child table
Build an array of IDs and then use that in your 3 queries with the
ANY operator.
