[pgadmin-support] Double-quoted table name, why ?

[Edward Leung]

Dear Supporter,
 
I am a fresh learner of PostgreSQL 8.2 under Windows 2000 and use PgAdminIII 
to manage the system.
 
I wonder why I need to double-quote the table name to get the table result 
or I get the ErrorCode: 42P01 without double-quotes.  Under the standard SQL 
syntax, there is no need to do so.
 
Under the PgAdminIII help document, there is no double-quote shown in 
examples. 
 
Question:  Can I config NOT to use the double-quote for selecting a table ?
 
 
Regards,
Edward
