In the post below the OP shows the tables involved(they where inherited):
http://www.postgresql.org/message-id/cadbmknm_y9ewdawdq_8dj1muc0z_fgwtyad2rwchgexj2jv...@mail.gmail.com
Still I did not think there was a restriction that constraint names be unique
across a database or cluster:
test=> create table tbl_a (fld_1 int CONSTRAINT fld_1_chk CHECK(fld_1 > 0) );
CREATE TABLE
test=> create table tbl_b (fld_1 int CONSTRAINT fld_1_chk CHECK(fld_1 > 0) );
CREATE TABLE
test=> \d tbl_*
Table "public.tbl_a"
Column | Type | Modifiers
--------+---------+-----------
fld_1 | integer |
Check constraints:
"fld_1_chk" CHECK (fld_1 > 0)
Table "public.tbl_b"
Column | Type | Modifiers
--------+---------+-----------
fld_1 | integer |
Check constraints:
"fld_1_chk" CHECK (fld_1 > 0)
