Bug reference: 5364
Logged by: Markus Wichitill
Email address: ma...@gmx.de
PostgreSQL version: 8.4.2
Operating system: Linux, Win7
Description: citext behavior when type not in public schema
Details:
Comparisons with columns of type citext silently work case-sensitively
without any error message, unless the search_path contains "public", even if
the type is not located in "public", but in the same schema as the table
using it.
I don't know if this is a bug or if it's specific to citext, but it's
surprising behavior.
shell> psql template1 pgsql
template1=# CREATE DATABASE db;
CREATE DATABASE
template1=# \c db
psql (8.4.2)
You are now connected to database "db".
db=# \i /usr/local/pgsql/share/contrib/citext.sql
SET
CREATE TYPE
[...]
db=# CREATE SCHEMA sch;
CREATE SCHEMA
db=# ALTER TYPE citext SET SCHEMA sch;
ALTER TYPE
db=# SET SCHEMA 'sch';
SET
db=# CREATE TABLE tbl (col citext);
CREATE TABLE
db=# INSERT INTO tbl (col) VALUES ('val');
INSERT 0 1
db=# SELECT col FROM tbl WHERE col = 'VaL';
col
-----
(0 rows)
db=# SET search_path = sch, public;
SET
db=# SELECT col FROM tbl WHERE col = 'VaL';
col
-----
val
(1 row)
