Обсуждение: BUG #4337: psql -c case insensitive

The following bug has been logged online:

Bug reference:      4337
Logged by:          none
Email address:      nomind@mailinator.com
PostgreSQL version: 8.2.3
Operating system:   windows xp
Description:        psql -c case insensitive
Details:

I'm programming an application that uses psql (...) -c "ALTER DATABASE
\"MyBase\" RENAME TO \"MyBase2\" and it doesn't work because it looks for a
"mybase" database name.

I'm using c# respecting case sensitive arguments, so I think the error is
with psql.

Check it ;)

Works for me.  I speculate that your scripting language is losing the
embedded double-quotes somewhere before psql gets them.  I don't know
much about Windows scripting so it's hard to say more than that; but
an extra interpretation pass over the command string would probably
cause such a problem.

Most likely you're bit by the completely insane rules of quoting in the
windows commandshell. See for example the comments around it in
src/port.h in the PostgreSQL distribution.
