varchar.diff
------------
This patch was necessary for the OpenLink Postgres Database Agent.
I think this fixes a bug anyway.
The following query demonstrates this bug:
create table foo (bar varchar);
insert into foo values (''); -- no problem
select * from foo where bar = ''; -- fails
fsync.diff
----------
This patch adds an option to disable synchronous writes.
It adds an extra option to postgres: -F
When started with -F, all fsync() calls will be no-ops,
so you'll be in big trouble when your machine suddenly crashes and your disk
cache is not flushed.
Use at your own risk (but it is *much* faster with large inserts)
This also speeds up initdb for initial database bootstrapping
To start postmaster with this "feature" enabled, type
postmaster -o -F -S
