PQregisterThreadLock().
I also remove the crypt() mention in the libpq threading section and
added a single sentence in the client-auth manual page under crypt().
Crypt authentication is so old now that a separate paragraph about it
seemed unwise.
I also added a comment about our use of locking around pqGetpwuid().
unlike template0 and template1 does not have any special status in
terms of backend functionality. However, all external utilities such
as createuser and createdb now connect to "postgres" instead of
template1, and the documentation is changed to encourage people to use
"postgres" instead of template1 as a play area. This should fix some
longstanding gotchas involving unexpected propagation of database
objects by createdb (when you used template1 without understanding
the implications), as well as ameliorating the problem that CREATE
DATABASE is unhappy if anyone else is connected to template1.
Patch by Dave Page, minor editing by Tom Lane. All per recent
pghackers discussions.
postgresql.conf.
---------------------------------------------------------------------------
Here's an updated version of the patch, with the following changes:
1) No longer uses "service name" as "application version". It's instead
hardcoded as "postgres". It could be argued that this part should be
backpatched to 8.0, but it doesn't make a big difference until you can
start changing it with GUC / connection parameters. This change only
affects kerberos 5, not 4.
2) Now downcases kerberos usernames when the client is running on win32.
3) Adds guc option for "krb_caseins_users" to make the server ignore
case mismatch which is required by some KDCs such as Active Directory.
Off by default, per discussion with Tom. This change only affects
kerberos 5, not 4.
4) Updated so it doesn't conflict with the rendevouz/bonjour patch
already in ;-)

that is, files are sought in the same directory as the referencing file.
Also allow absolute paths in @file constructs. Improve documentation
to actually say what is allowed in an included file.
listen_addresses parameter, as per recent discussion. The default behavior
is now to listen on localhost, which eliminates the need for the -i
postmaster switch in many scenarios.

comments/examples in pg_hba.conf. This patch remedies that, adds a brief
explanation of the connection types, and adds a missing period in the
docs.

modes (and replace the requiressl boolean). The four options were first
spelled out by Magnus Hagander <mha@sollentuna.net> on 2000-08-23 in email
to pgsql-hackers, archived here:

My original less-flexible patch and the ensuing thread are archived at:

Attached is a new patch, including documentation.
To sum up, there's a new client parameter "sslmode" and environment
variable "PGSSLMODE", with these options:
sslmode description
------- -----------
disable Unencrypted non-SSL only
allow Negotiate, prefer non-SSL
prefer Negotiate, prefer SSL (default)
require Require SSL
The only change to the server is a new pg_hba.conf line type,
"hostnossl", for specifying connections that are not allowed to use SSL
(for example, to prevent servers on a local network from accidentally
using SSL and wasting cycles). Thus the 3 pg_hba.conf line types are:
pg_hba.conf line types
----------------------
host applies to either SSL or regular connections
hostssl applies only to SSL connections
hostnossl applies only to regular connections
These client and server options, the postgresql.conf ssl = false option,
and finally the possibility of compiling with no SSL support at all,
make quite a range of combinations to test. I threw together a test
script to try many of them out. It's in a separate tarball with its
config files, a patch to psql so it'll announce SSL connections even in
absence of a tty, and the test output. The test is especially informative
when run on the same tty the postmaster was started on, so the FATAL:
errors during negotiation are interleaved with the psql client output.
I saw Tom write that new submissions for 7.4 have to be in before midnight
local time, and since I'm on the east coast in the US, this just makes it
in before the bell. :)
