Unquoted identifiers are always smashed down to lowercase. Quoted
identifiers are taken verbatim, including case.

This is not a bug: it's documented in
http://www.postgresql.org/docs/8.1/interactive/sql-syntax.html#SQL-SYNTAX-IDENTIFIERS .  Oracle has the same behavior, but uppercase unquoted identfiers. I seem to recall reading that the SQL spec requires that identifiers be treated as one or the other, but doesn't say which (upper or lower). 

rkh(at)csb-dev=> create temp table test (lccol text, Uccol text, ALLUCCOL
text, "lccol_q" text, "Uccol_q" text, "ALLUCCOL_q" text);
CREATE TABLE
Time: 233.815 ms

rkh(at)csb-dev=> \d test
    Table "pg_temp_1.test"
   Column   | Type | Modifiers
------------+------+-----------
 lccol      | text |
 uccol      | text |
 alluccol   | text |
 lccol_q    | text |
 Uccol_q    | text |
 ALLUCCOL_q | text |


-rEecE (take your pick on case)
