# Ticket [985771e1161200ae5eac3162686ea6711c035d08]:
#
# When both a main database table and a TEMP table have the same name,
# and a main database trigge is created on the main table, the trigger
# is incorrectly bound to the TEMP table. For example:
#
# CREATE TABLE t1(x);
# CREATE TEMP TABLE t1(x);
# CREATE TABLE t2(z);
# CREATE TRIGGER main.r1 AFTER INSERT ON t1 BEGIN
# INSERT INTO t2 VALUES(10000 + new.x);
# END;
# INSERT INTO main.t1 VALUES(3);
# INSERT INTO temp.t1 VALUES(4);
# SELECT * FROM t2;
#
# The r1 trigger fires when the value 4 is inserted into the temp.t1
# table, rather than when value 3 is inserted into main.t1.

# The following syntax really should not be allowed:
#
# CREATE TRIGGER xyz.trig BEFORE UPDATE ON xyz.tab BEGIN ...
#
# But a long-standing bug does allow it. And the "xyz.tab" slips into
# the sqlite_master table. We cannot fix the bug simply by disallowing
# "xyz.tab" since that could break legacy applications. We have to
# fix the system so that the "xyz." on "xyz.tab" is ignored.
# Verify that this is the case.
