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.
