In the 10+ years of pgAdmin, no-one has ever asked to have additional
SQL run by the View Data tool - what would be the point? You wouldn't
be able to have it create the temp table you want to view because you
need to know what table to view before you run the tool.

If you need that level of flexibility, then use the query tool where
you can create and use the temp table in one session. Failing that, if
you really want to use multiple tools on the same temp table, you'll
need to get someone in the community to implement global temp tables -
though really they're exactly the same as any other table (pretty much
the whole point of the temp table is that it's session-specific, and
isn't accessed through shared memory like regular tables).
