Back out the part of the change in [88a05141c28e5ff1] that adds affinity to
...
the materialization of a view, as the affinity can be undefined for a compound
query. This passes all TCL tests, but shows failures in the TH3 tests derived
from [forum:/forumpost/6f842bc5b2dadcb2|forum post 6f842bc5b2dadcb2], presumably
because the WHERE clause of the query uses constraints of the form
"source_crs_code='8675'" instead of "source_crs_code=8675". Perhaps further
changes on this branch should reimplement affinity on joins in cases where
the affinity is unambiguous.

Further fix for ticket [57c47526c34f01e8]. If a subquery has a result set
...
column of the form "CAST(expr AS NUMERIC)" do not give that column NUMERIC
affinity. NUMERIC affinity always goes to an integer if able, but a CAST
to numeric is a no-op if the input is a number. So the two are not equivalent.

If a subquery has a result column of the form "CAST(... AS NUMERIC)" then
...
give that column no affinity rather than NUMERIC affinity. This is because
casting to numeric preserves real values that could be integers but numeric
affinity does not. By using no affinity on the column, we make the behavior
consistent if the subquery is implemented as a co-routine or is materialized.
