Re: BUG #2294: SPI_connect() fails in trigger when a Foreignkey constraint exists on same table as trigger.

It entirely does, since the given code is missing SPI_finish().
Moreover, adding the SPI_finish() makes it work, according to my
testing.

With code as given:

regression=# insert into test_table1 values ('abcd', 'group');
INFO: t2294.c(35) Trigger start
INFO: t2294.c(43) SPI_connect OK
INFO: t2294.c(44) Trigger end OK
ERROR: SPI_connect failed
regression=#

With SPI_finish() added just before return statement:

regression=# insert into test_table1 values ('abcd', 'group');
INFO: t2294.c(35) Trigger start
INFO: t2294.c(43) SPI_connect OK
INFO: t2294.c(44) Trigger end OK
ERROR: insert or update on table "test_table1" violates foreign key constraint "test_constraint1_fk1"
DETAIL: Key (groups)=(group) is not present in table "test_table2".
regression=# insert into test_table2 values('group');
INSERT 0 1
regression=# insert into test_table1 values ('abcd', 'group');
INFO: t2294.c(35) Trigger start
INFO: t2294.c(43) SPI_connect OK
INFO: t2294.c(44) Trigger end OK
INSERT 0 1
regression=#

I think you had some pilot error in your testing ... perhaps forgetting
to reload the shared library after recompiling?
