Oleg,
Thanks for your prompt reply.
Actually, I am able to create a new access method for testing and add an
operator class for the type "integer" using the new access method. Then
created a table with two integer fields, one indexed using the new access
method and the other using a btree index, a
Ramy,
glad to hear from you !
AFAIK, posgresql doesnt' supports several indices for the same type.
I think this is a problem of optimizer. Probably other hackers know
better. I forward your message to -hackers mailing list which is a
relevant place for GiST discussion.
regards,

Daniel,
concurrency is a big issue of current implementation of GiST.
But it should don't bite you for READ ops !
-hackers mailing list is a very relevant mailing list for GiST
discussions. It's pity we several times claimed to work on GiST
concurrency and recovery, but never got a chance :)
I see
Does anyone know what the expected range of the "penalty" GiST method
is? (i.e. Is the legal range documented anywhere? Failing that, what
does existing GiST-based code expect?)
While rewriting gistchoose() in gist.c to be less obfuscated, it
occurred to me that (a) I don't think the existing code
Hi,
When doing CREATE or REPLACE FUNCTION of a builtin function, it seems to
have no effect if its in the 'C" language. SQL functions seem to work,
but as neilc pointed out, it may be due to the SQL function being
inlined.
The builtin function is still called, not the userdefined function for
'C'

I'd like to propose that we get rid of GUC's USERLIMIT category and
convert all the variables in it to plain SUSET. In my mind, USERLIMIT
is a failed experiment: it's way too complicated, and it still doesn't
do quite what it was intended to do, because there are times when it
can't check whether

I was thinking about organizing the translation files in a more efficient
manner. (not for 8.0, obviously)
Right now we have one PO file for each combination of program (or library) and
language. The idea was that one only has to install the translation files
for the PostgreSQL pieces that one
Awhile back, there was some discussion about pre-folding now() and

This is only available if you log all queries, which isn't normally done
while you are in production. When you hit a

Dear Folks,
Could someone be so kind to give me some pointers about how
to debug pg. I would like to know which debugger you use under windows and
linux
