Attempt to treat the arguments to a table-valued function as if they occur in the ON clause of a LEFT JOIN rather than in the WHERE clause.

21:07
Defer opening the file used for the temp database (where CREATE TEMP TABLE tables are stored) until the database is too large to reside entirely within the cache. There are likely still problems on this branch. check-in: be5a549e user: dan tags: tempfiles-lazy-open
20:59
Carry table column types through into VIEW definitions, where possible. check-in: fb555c3c user: drh tags: trunk
