Обсуждение: CREATE USER bug

Hello,
 It seems to me that the below should not be able to happen.



postgres=# create user with encrypted password '98wq7912a';
CREATE USER
postgres=# create user with encrypted password '98wq7912a';
ERROR:  CREATE USER: user name "with" already exists


Sincerley,

So, what are we doing about this? If we're considering it a bug, one way
to fix it is to move WITH from unreserved_keywords to reserved_keywords.
Any other suggestions?

I think the code is fine as it is now, seeing how WITH is optional:
      CREATE USER username [ [ WITH ] option [ ... ] ]

I don't see a huge problem with allowing "with" as a user name.  Of
course, we could require them to write:
      CREATE USER with WITH ...

but then WITH isn't optional anymore, at least for a user named 'with'.

It's not a bug.
