drh 01d230ce05 A list of arguments following a table name translates into equality 
constraints against hidden columns in that table.

drh 8a48b9c0b1 Minor refactor of the SrcList object so that it is able to hold the argument 
list to a table-valued-function in the FROM clause.

drh 398f872d1f Virtual table modules with a null xCreate method act as eponymous-only modules - 
they cannot be used in a CREATE VIRTUAL TABLE statement.  Add the series.c
extension that implements a postgres-like generate_series virtual table to
demonstrate this capability.

drh fa4620b6f5 Allow a VIEW to reference undefined tables and functions when initially 
created.  The error report is deferred until the VIEW is used.  This allows
views to be created before subviews and tables that the view references.

drh 8ea60e35c2 The "PRAGMA cache_size" reads the database schema, as it has down in all prior 
versions of SQLite.  This side-effect of cache_size is undocumented, but 
apparently it does get used and its absence from 3.8.11 was causing problems.
