Better estimatedCost in the xBestIndex method of the generate_series vtab. file: [235d6281] check-in: [f2c16094] user: drh branch: trunk, size: 12697

Fix a corner-case bug in table-valued functions. Update the generate_series() virtual table to increase the performance estimate penalty for being underspecified. file: [b8fb7bef] check-in: [552bc9cb] user: drh branch: trunk, size: 12677

Fix corner-case memory management issues in table-valued functions. Change virtual table handling so that if xDestroy is missing the table is eponymous only even if xCreate is present. file: [6f94daf5] check-in: [774e6a14] user: drh branch: trunk, size: 12591

Prevent the series.c extension from loading on older versions of SQLite that do not support xCreate==NULL. file: [610bf80e] check-in: [3efc7942] user: drh branch: table-valued-functions, size: 12550

Fix eponymous virtual tables so that they do not automatically make the first column the rowid. Enhance the generate_series virtual table to support rowid. file: [5b84c658] check-in: [a325a085] user: drh branch: table-valued-functions, size: 12380

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. file: [c2be7ee4] check-in: [c58426db] user: drh branch: table-valued-functions, size: 7463 Added
