Please enter a FULL description of your problem:
------------------------------------------------

NUMERIC type cannot be used in an INDEX.

Please describe a way to repeat the problem.   Please try to provide a
concise reproducible example, if at all possible: 
----------------------------------------------------------------------

Method (1) using primary key syntax:
scdrought=> create table foo ( f1 NUMERIC(3,0) primary key );
NOTICE:  CREATE TABLE/PRIMARY KEY will create implicit index 'foo_pkey' for table 'foo'
ERROR:  Can't find a default operator class for type 1700.


Method (2) do it by hand.
mschout=> create table foo (f1 NUMERIC(3,0));
CREATE
mschout=> CREATE UNIQUE INDEX foo_pkey ON foo (f1);
ERROR:  Can't find a default operator class for type 1700.
