Is this normal Postgres / psql behavior?
griffindb=# \d system.user;
Table "system.user"
Column | Type | Modifiers
-----------+-----------------------+--------------------------------------------
--------
username | character varying(20) | not null
password | character varying(32) | not null
firstname | character varying(40) | not null default 'nema ime'::character vary
ing
lastname | character varying(40) | not null default 'nema prezime'::character
varying
Indexes:
"SystemUser_PK" PRIMARY KEY, btree (username) CLUSTER
normal query:
griffindb=# select * from system.user where username = 'root';
username | password | firstname | lastname
----------+----------------------------------+-----------+---------------
root | 1e7db545fccbf4e03abc6b71d329ab4f | Super | administrator
(1 row)
error query:
griffindb=# select * from system.user where user = 'root';
username | password | firstname | lastname
----------+----------+-----------+----------
(0 rows)
column user does not exist should throw an error!
PostgreSQL / psql version: 9.1.3 on Windows 7 64-bit
Should Postgres or psql report an error because column used in WHERE clause does not exist?

"user" is actually a function the returns the current_user. It is an SQL special function and thus does not require the use of () after the function name. So basically you are saying "where current_user = 'root'" which is either a constant true or false for the statement.
