RE: changes to table creation syntax in 7.1.2?

Jason,

First of all, thanks for your response. I had given up that anyone was going
to respond. After seeing your response I went back and found what was making
the difference. The failing syntax below worked on 7.0.3 but not on the
7.1.2 version. Seeing your working example(unlike another response) gave me
the answer.

Jayson

This file of commands fail...

[jayson(at)grendal db]$ cat test
CREATE TABLE "test_cat" (
"uid" int4 NOT NULL,
"name" text NOT NULL,
"description" text NOT NULL,
"parent_category_uid" int4 NULL REFERENCES test_cat(uid)
);
CREATE UNIQUE INDEX test_cat_pkey on test_cat (uid);
[jayson(at)grendal db]$ psql -e -f test -d wr -U wr_web
CREATE TABLE "test_cat" (
"uid" int4 NOT NULL,
"name" text NOT NULL,
"description" text NOT NULL,
"parent_category_uid" int4 NULL REFERENCES test_cat(uid)
);
CREATE UNIQUE INDEX test_cat_pkey on test_cat (uid);
psql:test:6: NOTICE: CREATE TABLE will create implicit trigger(s) for
FOREIGN KEY check(s)
psql:test:6: ERROR: UNIQUE constraint matching given keys for referenced
table "test_cat" not found
[jayson(at)grendal db]$

While this set of commands is successsfull...

[jayson(at)grendal db]$ cat test
CREATE TABLE "test_cat" (
"uid" int4 PRIMARY KEY,
"name" text NOT NULL,
"description" text NOT NULL,
"parent_category_uid" int4 NULL REFERENCES test_cat(uid)
);
[jayson(at)grendal db]$ psql -e -f test -d wr -U wr_web
CREATE TABLE "test_cat" (
"uid" int4 PRIMARY KEY,
"name" text NOT NULL,
"description" text NOT NULL,
"parent_category_uid" int4 NULL REFERENCES test_cat(uid)
);
psql:test:6: NOTICE: CREATE TABLE/PRIMARY KEY will create implicit index
'test_cat_pkey' for table 'test_cat'
psql:test:6: NOTICE: CREATE TABLE will create implicit trigger(s) for
FOREIGN KEY check(s)
