Folks,
Please help update the wiki page around how to beta test. Particularly,
please update it with particular things we'd like to see users test for,
like data corruption related to freezing (with some notes on how to test
for this).

You could try to change the ident method to trust (in pg_hba.conf). This
should allow you to login.
Then, set the password of the postgres user (alter user postgres with password
'blabla1212' ; ). Then you could change the ident method back to md5 .

Through googling, i found that Normal Disk has external data transfer rate of
around 40MBps,

Does this includes, seek and rotational latency ?

I think 40MB/s is a burst speed. You should do some

But, in PostgreSQL all costs are scaled relative to a page fetch. If we
make both sequential_page_fetch_cost and random_page_cost to 1, then we
need to increase the various cpu_* paramters by multiplying the default

In our case we are reading pages from Main Memory File System, but not from
Disk. Will it be sufficient, if we change the default values of above
paramters in src/include/optimizer/cost.h and

Josh Berkus josh@agliodbs.com writes:
I don't see why you're increasing the various cpu_* costs.
You missed the point Josh --- these numbers are relative to the cost of
a page fetch, so if page fetch is measured in microseconds instead of
milliseconds, then you *do* want to bump the CPU costs
Since sequential access is not significantly faster than random access in a
MMDB, random_page_cost will be approximately same as sequential page fetch cost.
As every thing is present in Main Memory, we need to give approximately same
cost to read/write to Main Memory and CPU Related
Hi,
I'm very new to this list -- I've been using and advocating PostgreSQL for
no less than 4 or 5 years now, and have participated in some of the other
mailing lists, but never on this one.
My question is (short version): how would one go about adding a new
(built-in) function to PostgreSQL?

Actually, there is probably comparatively little to gain from making it
a builtin. And SHA1 is already there in the pgcrypto contrib module.
Presumably if we wanted a builtin we would start from that code base.
