Dear Gurus,
Version: 7.3.3, 7.4.8
I don't know for sure, but something like this happened when dumping our server from 7.3 to 7.4. Actually, it seems to be a problem in 7.4 (maybe also in 7.3, but unlikely -- see below, "our original way").
# create table foo (bar int, constraint foobar check (true or bar=1));
CREATE TABLE
# \d foo
Table "public.foo"
Column | Type | Modifiers
--------+---------+-----------
bar | integer |
Check constraints:
"foobar" CHECK (true OR bar = 1)# drop table foo;
DROP TABLE
# create table foo (bar int, constraint foobar check (true));
CREATE TABLE
# \d foo
Table "public.foo"
Column | Type | Modifiers
--------+---------+-----------
bar | integer |
Check constraints:
"foobar" CHECK ()Yours, -- G.
---------------- our original way we found the problem:
-- original create command:
CREATE TABLE foo (
bar int,
CONSTRAINT foobar CHECK (true or bar=1)
);-- 7.3 dump:
CREATE TABLE foo (
bar int,
CONSTRAINT foobar CHECK (true)
);-- fed to 7.4, then \d
...
Check constraints:
"foobar" CHECK ()
-- note the empty parentheses!-- mirroring the database caused: ERROR: syntax error at or near ")" at character xxx
-- recreated table (actually, readded constraint) to 7.4, then \d
...
Check constraints:
"foobar" CHECK (true OR bar=1)
