Description:

Hi,
When I use the money type as the key to create the partition table as
follows:

postgres=# create table test(m money) partition by list(m);
CREATE TABLE
postgres=# create table test_1 partition of test for values in (10);
CREATE TABLE

Partition bounds without apostrophe can be createed, but it store the null
value，not '10' value.

In fact, Correct grammar for creating partition is with apostrophe like
this:
postgres=# create table test_1 partition of test for values in ('10');

But the first creating partition without apostrophe should report an error
like "ERROR: operator does not exist: money = integer" as adding a check
constraint.

Looking forward to your reply.
