Question

So I made some tables programatically and I want to verify it’s structure is what I think it is.

>Rocko=# \c Rocko
Password for user Rocko:
psql (8.4.4, server 8.4.8)
You are now connected to database "Rocko".
Rocko=# \d
            List of relations
 Schema |     Name     |   Type   | Owner
--------+--------------+----------+-------
 public | Email        | table    | Rocko
 public | Email_id_seq | sequence | Rocko
 public | Test         | table    | Rocko
 public | Test_id_seq  | sequence | Rocko
 public | User         | table    | Rocko
 public | User_id_seq  | sequence | Rocko
(6 rows)

So, for example, I want to see the columns in Test.

Rocko=# \d Test

Did not find any relation named "Test".

Wait a minute?! Did not Test just show up under “List of Relations”? What’s going on here?

Answer 1

PostgreSQL converts unquoted identifiers (such as table and column names) to lower case by default; the standard says that identifiers are supposed to be normalized to upper case but that’s not important here. So, when you say this:

\d Test

PostgreSQL considers that the same as \d test. You probably have a table that was created with a quoted name:

create table "Test" ( ...

so that its name is case sensitive and must be quoted (with double quotes) every time it is referenced. So try quoting the name:

\d "Test"
