Обсуждение: Blocking object creation for some users

Is there a way to keep users from creating new objects in a database
while letting them access existing objects in the same database?

It doesn't look like there is a clean (e.g. with GRANT) way to do this. I
tried looking to see if there was a sneaky way to block update access to some
of the system tables, but that doesn't seem to be doable either.

Hello all:

Been seeing a worsening problem on a number of my servers lately. I'm using
postgres as a backend to PHP applications, hosted on Apache. At one
particular point in the application (always in the web-side login, which is
probably significant), my web browser returns a "could not connect" error.

Scanning the logs, I find this in the postmaster log:

pq_recvbuf: unexpected EOF on client connection

And this in the Apache error log:

[Wed Feb 20 21:29:52 2002] [notice] child pid 18595 exit signal Segmentation
fault (11)

There seem to be a lot of reasons why child processes die in this way in
Apache. Does anyone know of any specific to postgres/PHP?

Thanks,

steve

sounds like your apache process (probably with a DSO PHP) died
unexpectedly (any coredumps?) before it was suppose to complete the
transaction with PostgreSQL backend.

it could be anything that cause this. without a trace or further system
configuration, it would be hard to tell you what's going on.

I have never seen this with JSP. Something wrong with your php code.

Yes, it's a DSO PHP. Eh, coredumps! Where would I look (betrays his helpless
ignorance).
