Thread: BUG #3079: pg_dump doesn't dump datascheme with uppercase letters in

The following bug has been logged online:

Bug reference:      3079
Logged by:          Eugene
Email address:      eugenekuz@mail.ru
PostgreSQL version: 8.2.0 - 8.2.3
Operating system:   WinXP
Description:        pg_dump doesn't dump datascheme with uppercase letters
in
Details:

When a datascheme contains uppercase letters in its name, pg_dump doesn't
recognize the scheme as valid
It prints "No matching schemas were found"

Ex.
There are a scheme with name "Schema".

>pg_dump -n "Schema" -U postgres database
pg_dump:No matching schemas were found


rename "Scheme" to "schema" then
>pg_dump -n "Schema" -U postgres database
...
...

Works good

P.S.
in postgresql-8.1 package it works anyway

This is not a bug.  The problem is that there are two levels of quoting
needed: one for the shell and one for SQL.  As you wrote it, the double
quotes are stripped off by the shell and so pg_dump gets Schema, which
is case-folded per normal SQL rules.  So you need to write

    pg_dump -n '"Schema"' -U postgres database

Now, the shell eats the single quotes and passes "Schema" to pg_dump.
