Dear hackers Sorry for not replying the patch review. I didn't see the

notice the one for me, my mail box configuration problem. I am still kind
of busy with my university final year project. I shall not have
Hi, Dear HackersI need to estimate the hashjoin cost in my research. As the
textbook shows, it is 3(R+S) where R and S are the size of the tablesize of the
two tables, which realistically only considers the cost of IO. But this is

Hi, hackersI was exporting my project to a patch file. As the patch review

now?

Hi, hackersI modified the code in add_path() a bit so that all the query
path candidates inside pathlist will not be removed and all new path will be
added into the pathlist, thus all path candidates are kept in pathlist. I then
tested a four-relation query. In 9.1.3, I can see thousands
[ shrug... ] When you're not showing us exactly what you did, it's hard
to answer that for sure. But there is some prefiltering logic in

Hi, Heikki
1. We probably don't want the SQL syntax to be added to the grammar.
This should be written as an extension, using custom functions as the
API, instead of extra SQL syntax.
2. It's not very useful if it's just a dummy replacement for WHERE
random() ?. It has to be more
