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.
