ed07d0ea76 If the SELECT that implements a subquery or a VIEW or a CREATE TABLE AS is 
a compound with different result datatypes on two or more arms of the compound,
then the overall column type becomes BLOB (ANY).

a8b5c8739c 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.

7ca4312ff2 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.

FossilOrigin-Name: f0325359d5795237b79f90f21b42d7d942c7e918137cb0231d404365d3041e81

89e160a96a 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.
