4f16ff9d06 Follow-up to [68db1ff9c44fa9c3]: The number of registers needed by
PRAGMA foreign_key_check was increased too late for an assert() deep
down inside of sqlite3ExprCode().  So move the size increase a little
earlier.

5c46a7e555 In the PRAGMA foreign_key_check, ensure that sufficient registers are
allocated for the virtual machine, even if one or more foreign keys reuses
the same column multiple times and has more columns than the table it is part
of.  [forum:/forumpost/a6b0c05277|Forum post a6b0c05277].

foreign key constraints.

68a494c06f Fix a problem causing SQLite to return false "foreign key violation" errors
when there is a partial (i.e. WHERE constrained) UNIQUE index on the parent
key columns. This bug did not cause SQLite to allow illegal data to be
inserted into the database, only to reject legal operations.

648e264342 Add the "defer_foreign_keys" pragma and the SQLITE_DBSTATUS_DEFERRED_FKS
value for sqlite3_db_status().  This is a cherry-pick of a sequence of five
checkins in the sessions branch between [1d44e5d3c2] and [d39e65fe70].

60218d2a0e The FOR EACH STATEMENT clause in a trigger is now a syntax error. It used
to be silently ignored.  STATEMENT is no longer a keyword. (CVS 3821)

85c23c61e2 Increased test coverage. Some malloc tests now fail though this is believed
to be an instrumentation problem not a real error. (CVS 2604)
